PEP8 underscore_function_names vs camelCaseFunctionNames

[DerThorsten]

@constantinpape I am thinking of using PEP8 function names with underscores and variables names with underscores for the python part of nifty.
I still in favour four camelCase function in C++.

Would you consider this to be a good idea?
Pro:

• python de facto uses underscore / PEP8

Con:

• cpp uses camelCase
• I like camelCase
• a lot of files to touch

What would you say? Is it worth the refactoring?
