Tkinter Tutorial Python Pdfminer3k
Since I want to move from python 2 to 3, I tried to work with pdfmine.3kr in python 3.4. It seems like they have edited everything. Their change logs do not reflect the changes they have done but I had no success in parsing pdf with pdfminer3k. For example:
Since I want to move from python 2 to. Pdfminer3k has no method named create_pages in. From a pdf file the following code works with pdfminer3k using python 3.4. A first, practical look at one of Python's graphical toolkits - TkInter. We show you a 'Hello World' example, and a glance at the power of TkInter.
They have moved PDFDocument into pdfparser (sorry, if I spell incorrectly). PDFPage used to have create_pages method which is gone now. All I can see inside PDFPage are internal methods. Does anybody has a working example of pdfminer3k? It seems like there is no new documentation to reflect any of the changes.

If you are interested in reading text from a pdf file the following code works with pdfminer3k using python 3.4.

Perhaps,you could use pdfminer.six.It's description:

After installing it using pip:
pip install pdfminer.six
The usage of it is just like pdfminer, at least in my code.
