No, C doesn't support exception handling. As a result, handling error
conditions in C is a huge pain for which (forward-only) goto is often,
while not the only remedy, the least painful one. Or if you've really
developed a need for self-harm, setjmp/longjmp. Or, as is more
frequently the case in code in the wild, error conditions simply don't
get checked for and come as a surprise and/or segfault later on.
Python is a radically higher level language than C. Python supports
different structures than C, largely and specifically so that you don't
have to do things in some of the error-prone ways you would do them in
C. Therefore, a given task should be solved differently in Python than
I try very hard to write Python when I write Python, and to write C when
I write C. And to write through the tears when I write C++.
