Is it possible to use gfx class in python on Google app engine? I need to convert PDF files to image files.
As gfx module need to bepiled in host you can't use it in Google App pure python extensions can be used. All code for the Python runtime environment must be pure Python and not include any C extensions or other code that must bepiled.
How do I extract text and images from PDF files using Python and convert it into a PDF?
import PyPDF2 pdf_file = open('') read_pdf = (pdf_file) number_of_pages = () page = () page_content = () print page_content Use these import if above code not work import ract = (path)
How can I convert a PDF to XML?
Disclaimer Im the founder of s a software solution specialised in transforming semi-structured documents (invoices purchase orders reports ) into structured data such as XML CSV JSON. As already mentioned by other there is unfortunately no easy way to convert PDF to XML files. This is simply because the PDF format doesn include any structuring tags like for example HTML does. A PDF file includes in most cases just a flat description of the visual representation of its content. Which means that there are no indicators which would allow you to easily identify hierarchical data and key data points. Some PDF files actually do have XML data stored in their metadata though. For example electronic PDF invoices might have all relevant key data inside the document metadata. But at the time of writing PDFs containing XML data are rather the exception. But there are still ways to convert PDF to XML s ! You have basically two different problems here to solve First you need to get hold of all and s. The way we do it at Docparser is to check if we can extract data and pipe the files through a OCR library if no was returned. In either case I would rmend to rely on Linuxmand line utilities. While you might also find a Python library the Linuxmands usually work much better in my experience. In case we need to handle scanned s as well as hidden returned by the OCR. Once you are sure that the PDF file contains data you can use the Linuxmand line tool PdfToText s with the option - layout. You should then have a representation of your PDF file which has (nearly) the same layout. Convert Extracted Text Into Structured Data This one is difficult to answer without knowing your specific use-case. Converting unstructured or semi-structured into a XML structure can be easy challenging or impossible. It really depends on the kind of data your are dealing with and how granular the output needs to be. At Docparser we developed a set of tools that can help you transform PDF documents such as invoices purchase orders delivery orders etc. into fine grained structured data objects without any coding. If this is something you would be interested in Ill be more than happy to ge you through our free trial.
What can Python do?
It nice that you want to know the applications of python before learning it. Python is a general purpose programming language. So it has vast number of applications in Artificial Intelligence Data analytics Web development 3D gaming and graphics Robotics etc. It relatively easy programming language to learn with simple syntax. No wonder it has be favorite of techmunity. Therefore it has been used in variety of fields. You can do software development using python. Popular applications like YouTube BitTorrent Dropbox have been using python heavily to build their functionality. A lot startups have been using python to build mobile applications. A popular app like Instagram which is mostly built using python. Yes you can develop websites using Python. You can use web frameworks like Django Pyramid Flask etc to create back end logic. Python has also standard library supports for internet protocols like HTML XML JSON etc. that are used in develop front end logic of the application. Data Science New buzzword in tech industry. Python has libraries like Pandas and NumPy that are used in Data Science and Data Visualization. They have capability do a lotputing and other host of other technical things. AI and ML have be hot fields in today world. A lot people have heard and used these words but they really don know what they mean at deeper level. Python provides library called Scikit-Learn library to write machine learning algorithms in python. If you are more into neural networks then python has Tensorflow to implement neural networks. You can also build Operating Systems using python. You heard it right. Although python is not known for its OS building capabilities I just wanted you to know that it is that robust. Moreover it is platform independent so applications build in python can run on any OS platform. Python is one of the best languages if you want to learn how to code. It usually better if you start with simple and versatile language like python. Now there are many resources that teach you python. I havee across Edu4Sure python course as one of the best courses to learn python. They have good mentors with strong focus on hands on learning. I hope this helps you. Best wishes!
