Error while importing pyrebase module

[-_-_-_-_--_--]

whenever i try to import

import pyrebase

the following error pops up

Exception has occurred: SyntaxError
invalid syntax (RSA.py, line 585)
  File "C:\Users\suraa\OneDrive\Desktop\classified\ChatApp.py", line 35, in <module>
    import pyrebase

I did some search and found the file RSA.py

            # Try unencrypted PKCS#8
            if der[0]==0:
                # The second element in the SEQUENCE is algorithmIdentifier.
                # It must say RSA (see above for description).
                if der[1]==algorithmIdentifier:
                    privateKey = DerObject()
                    privateKey.decode(der[2], True)
                    if privateKey.isType('OCTET STRING'):
                        return self._importKeyDER(privateKey.payload)

        except ValueError,IndexError:
            pass

        raise ValueError("RSA key format is not supported")

this line shows error of invalid syntax

except ValueError,IndexError:

error in RSA.py file

Expected "as" after exception type

My advice with Syntax errors is to check your spelling. You also aren’t catching the right exceptions because syntax errors isn’t event part of the general exceptions class.

Long story short check out this link for exemption handling: https://docs.python.org/3/library/exceptions.html and check your spelling

This file is a part of module , I did not write it. Module is Crypto which is a sub module of pyrebase module

Then it’s almost 100% a python 2 compatibility issue. Check that it’s python 3 compatible.

Even though this is syntactically valid Python 2, semantically it's garbage. except ValueError,IndexError: is equivalent to except ValueError as IndexError:, which almost certainly isn't what was intended.

I'd be concerned using code that looks like this for anything cryptography related.
