I'd like to try my hand at some PC game development.  I keep hearing that python is slow compared to C++.  Is this something I should be worried about?  
I am more familiar with python than C++.  If I'm looking to make some games, should I take the time to learn C++ or just stick with Python?
C++ is much more easier for object orientation.  When you're doing things, it's easier to keep track of everything, because most IDEs for C++ are more based on projects, were as IDLE is more based on single files.  
The bottom line is for game development, use what you're comfortable with using.  I mean, game development is about what you want to do, not what would be better, because better == what you want.
How "slow" is python for game development?
