Python Tutorial: Working with JSON Data using the json Module
This technique offers some unique benefits, and in some common use cases—most importantly, perhaps in your case—it can be much more efficient than the alternative. I encourage you to follow along. Writing Python would come later when you automate steps 2 — 5. We usually know in advance at least some of the content we want. The XML in content. Heck no!
For instance, if you see this in the XML—. So there you have it! I use a library called appy. Heard of it? Basically, It allows you to put some python code into your template, in fields and comments of writer documents.
It alse can be used, although with less complexity, in calc. Philip, I had the same thoughts as Marc when reading your post.

I really recommend that you have a look at appy. Note also that appy does not yet fully support Python 3. First of all, one of the advantages of the method I described is that you get to do most of your document creation work in LibreOffice rather than describing a document via Python code. The latter is so much more abstract. I could live with the Java flavor but the other points killed my enthusiasm. For that reason I created Pythonic wrapper.
Use one LibreOffice process for each application process, restart it after every few requests and be prepared to kill everything and retry on occasional errors. Thanks, Miloslav. I do not think that we are making a lot of Python-UNO calls. We are trying to minimize them because each of them takes some time. For example we are writing whole tables in one call. I guess that LibreOffice simply does not handle edge cases well.
I saw many segfaults when I passed invalid or out of range arguments to UNO calls. Also most attempts for concurrent access ended by error. It looks like it could be useful. I like the fact that it is not tied to a specific version of OpenOffice. Thanks for the tip! Skip to content. Create a LibreOffice document that will serve as a template for the documents you want to create.

Convert Text and Text File to PDF using Python
I am trying to write app in Python which will allow to convert xls file to pdf. What I want, is to generate printable pdf label with all this info for each index- big bolded index and below it prices. So basically the label should have big index, and these two prices, in other words one row should be one pdf page in exact size.
And it also needs to have simple gui- just 2 buttons, upload file and generate. I get the rows but now I have trouble to write it to pdf.
I can't find any lib that will suit my requirements. Could you please advise best lib for this app? If you're just reading from excel and then creating an original pdf, I would recommend just using pandas. For creating the pdf part, there are several options including pydf2pdfdocument and FPDF.
FPDF Documentation can be found here. I've posted a fully reproducible example below, using pandas and fpdf it also uses numpy to create a sample dataframe.
I loop through the whole dataframe in my example but you could select specific rows based on the index if you wanted to do so. Expected pdf output would look like this:. Learn more.

I have a database generated by a survey to evaluate university professors. What I want is a python script that takes the information from that database, generates a graphing table for each user, creates graphs for each user, and then renders it in a template to export it to a pdf. Each teacher has several categories assigned to be evaluated respect, wisdom, etc.
In other words, a category has several questions. Each row of the DB is the answer to a question from a student evaluating a teacher. I need to create a script for automatically generate pdf reports that summarizes this information through charts, for example a chart with the overall score of each teacher, another chart with the score of each teacher by category, another chart with the average of each student, etc.
Finally, every teacher would have a report. I want a report like this. And what would be the general process of doing so. I don't need the code, because I know the answer is very general, but the knowledge of how I could do it. For example: you would first need to process the information with pandas, to create a table that summarizes the information you want to graph, then plot it, then create a template of your report with XYZ module and then export it to pdf with XYZ module.
There are a lot of options for creating a pdf in python. FPDF Documentation can be found here. It's perhaps also good to think about what python modules you might want to use to create graphs and tables. In my example, I use matplotlib link to docs and I also use Pandas to create a dataframe using pandas.
I've posted a rather lengthy but fully reproducible example below, using pandas, matplotlib and fpdf. The data are a subset of what the OP provided in the question.PDFs are one of the most important and widely used digital media. It uses.
Creating PDF files using Python and reportlab
It is used to present and exchange documents reliably, independent of software, hardware, or operating system. Converting a given text or a text file to PDF Portable Document Format is one of the basic requirements in various projects that we do in real life. In this article, you will come to know the way to convert text and text file to PDF in Python. It is free to use and it does not require any API keys.
It means that any kind of modification can be done in PDF files. Now if we want to make the above program more advance what we can do is that from a given text file extract the data using file handling and then insert it into the pdf file. The approach is all same as above, one thing you have to do is extract the data from a text file using file handling. Note: Refer this article to know more about file handling in Python.

Python program to create.
Python program to convert. Check out this Author's contributed articles. Load Comments.The ReportLab toolkit allows you to create interactive fillable forms. The PDF standard actually has a fairly rich set of interactive elements. In this section, we will look at the following widgets:.
All of these widgets are created by calling various methods on the canvas. Note that you can only have one form per document. The checkbox widget is exactly what it sounds like.
As you can see, we set up the name and set the tooltip to basically match the name of the widget. Then we set its position and a few other things. If you turn it off though, the checkbox may become invisible, so you might want to set its background color via fillColor if you do that.
I set the buttonStyle to something different for each of the checkboxes. Here is what I get when I run the code:. If you open up the document and check all of the checkboxes, you will end up with them looking like this:. Radio widgets are kind of like checkboxes except that usually you put radio buttons into a group where only one radio button can be selected.
Checkboxes are rarely limited to just allowing one checkbox per group. ReportLab does not appear to have a way to explicitly group a set of radio boxes as being together. This appears to only happen implicitly.
In other words, if you create a series of radios one after the other, they will be grouped together. When you run this code, you will notice that you only get 3 radios. This is because you are required to create two instances of each radio button with the same name, but with different values and sections. This also allows you to change the appearance of the radio when it is selected or deselected. The choice widget is basically a combobox that displays a dropdown when the user clicks on it. This allows the user to pick one or more options from the drop-down list, depending on the fieldFlags you have set.
If you add edit to the fieldFlagsthen the user can edit item in the choice widget. In this example, we create two choice widgets with slightly different styles applied. Anyway, when you run this code, you will find that it generates something like this:. The listbox widget is kind of like the choice widget except that a listbox is a scrollable box instead of a combobox.
You can use the fieldFlags argument to allow the user to select one or more items from the listbox. This example is actually pretty similar to the previous one where we created the choice widget.
The main difference here is the look of the listbox widget versus the choice widget. Otherwise, they are pretty much the same.
Following is a screenshot of what this code generates:. The textfield is a text entry widget.
You will see these in forms for entering your name and address. Here we create a series of textfields with different settings applied to them. As you can see, we changed the border and background color on several of the fields. Then we just added some fairly standard ones. We also used the width parameter to change how wide the textfield is. In this article we learned how to create the various widgets that ReportLab supports for creating interactive PDF forms.
As you can see, ReportLab does provide all that you need to create fairly robust forms though. In this section, we will look at the following widgets: checkbox radio choice listbox textfield All of these widgets are created by calling various methods on the canvas.However it will cover more than enough for you to get started using it effectively.
At the time of writing, this command installed version 1. You will notice when you are installing this package that it has no dependencies, which is nice. Then enter the following code into it:. The first item that we need to talk about is the import. Here we import the FPDF class from the fpdf package. The defaults for this class are to create the PDF in Portrait mode, use millimeters for its measurement unit and to use the A4 page size.
If you wanted to be explicit, you could write the instantiation line like this:. If you go diving into the source, you will find that the PyFPDF package only supports the following page sizes:. This is a bit limiting compared to ReportLab where you have several additional sizes supported out of the box and you can set the page size to something custom as well.
Next we create a cell that is millimeters wide and 10 millimeters high. A cell is basically a flowable that holds text and can have a border enabled. The txt parameter is the text that you want to print in the PDF. We chose the latter here. Finally we save the document to disk by calling the output method with the path to the file that we want to save. You will note that Arial is not listed here even though we used it in the previous example.
Arial is getting remapped to Helvetica in the actual source code, so you are not really using Arial at all. The next step is to create a page and then loop over the core fonts. If there is one, we skip that font.
Otherwise we set the font and the font size and write it out. We also increase the font size by two points each time through the loop. However the number of core fonts is pretty small. This method takes the following arguments:. This is a really simply way to add fonts though and will probably work. Note that it uses the following search paths:. These appear to be constants that are defined either in your environment or in the PyFPDF package itself.

I'm working on a project which takes some images from user and then creates a PDF file which contains all of these images. Is there any way or any tool to do this in Python? I suggest pyPdf. It works really nice. I also wrote a blog post some while ago, you can find it here. It can only split and merge.
ReportLab is very extensive. All I needed is to get a bunch of images into a PDF, so that I can check how they look and print them. The above is sufficient to achieve that goal. ReportLab is great, but would benefit from including helloworlds like the above prominently in its documentation. I suggest Pdfkit. It creates pdf from html files. I chose it to create pdf in 2 steps from my Python Pyramid stack:. Sometimes a PDF document needs to be generated dynamically, however, and that can be quite a challenge.
Fortunately, there are libraries that can help. This article examines one of those for Python. Here is a solution that works with only the standard packages. You can create a figures with subplots, where each subplot is one of your images. You have full freedom to mess with the figure: Adding titles, play with position, etc. Once your figure is done, save to PDF. Each call to savefig will create another page of PDF.
I have done this quite a bit in PyQt and it works very well. Qt has extensive support for images, fonts, styles, etc and all of those can be written out to pdf documents. I believe that matplotlib has the ability to serialize graphics, text and other objects to a pdf document.
It supports embedding almost any kind of raster or vector images. It requires reportlabbut I found reportlab is not so straight forward to use at least for me. And often used. But maybe it was renamed from pyfpdf to fpdf. Basically just used subprocess to call tiff2pdf. If they aren't tiffs you could probably convert them to tiffs using PIL, or maybe find a tool more specific to your image type or more generic if the images will be diverse like ReportLab mentioned above.
If you are familiar with LaTex you might want to consider pylatex.
