pyPDF2 is throwing the attached error

pyPDF2

Actually, I need to list out broken links in the PDF file. Please suggest.

Which version of Python are you using? The .has_key method was removed in Python 3.0: https://docs.python.org/3.1/whatsnew/3.0.html#builtins

Hi,

Thanks for your reply! I am using Python 3.10 version.

Dear Manoj,

can you attach or give links to sample PDFs with ideally good and broken links and I will have a go at testing this.

@gilramanoj, Can you please provide PDF and code to investigate. Thanks

Closing this as it's an issue in user's code, not PyPDF2 itself.

As @Joshua-IRT indicates, the .has_key method on dictionary like objects (which PageObject is) was removed as part of python3 as it's recommended to use the in operator instead.

An example:

>>> from PyPDF2 import PdfReader
>>> pdf = PdfReader('PDF_Samples/GeoBase_NHNC1_Data_Model_UML_EN.pdf')
>>> pageObject = pdf.pages[0]
>>> pageObject
{'/Type': '/Page', '/Parent': IndirectObject(2, 0), '/Resources': {'/Font': {'/F1': IndirectObject(5, 0), '/F2': IndirectObject(8, 0), '/F3': IndirectObject(10, 0), '/F4': IndirectObject(12, 0), '/F5': IndirectObject(17, 0)}, '/XObject': {'/Image7': IndirectObject(7, 0), '/Image21': IndirectObject(21, 0)}, '/ProcSet': ['/PDF', '/Text', '/ImageB', '/ImageC', '/ImageI']}, '/Annots': [IndirectObject(19, 0), IndirectObject(20, 0)], '/MediaBox': [0, 0, 612, 792], '/Contents': IndirectObject(4, 0), '/Group': {'/Type': '/Group', '/S': '/Transparency', '/CS': '/DeviceRGB'}, '/Tabs': '/S', '/StructParents': 0}
>>> 'foo' in pageObject
False
>>> '/Type' in pageObject
True
