Yes, unless your C code is braindead buggy

Python is not a C interpreter.

newbie to programming, uh ?-)
How do you think this all works ?
the Python interpreter byte-compile and execute python source code, not
C source code. C being a compiled language, C source code is just text,
nothing you can execute before compilation (ie : transformation of
source code into machine code).
When you use a "C extension" in Python, you use in fact a
machine-language compiled extension. The 'C extension' term is faulty.
The fact is that the extenstion has generally been written in C before
compilation, hence the term, but open such an extension with your
favorite code editor, I can tell you you wont find anything like a C
source in it !-)
BTW, Python (I mean the Python interpreter) itself is written in C.
