My experience is that Python has *many* more memory leaks than C code.

They're less visible since I ran C code on a computer with 32MB of RAM, and I run Python code on a computer with 32GB of RAM, but they're very common in modern Python programs.

As another comment pointed out, memory issues in Python are less dangerous too. I'm glad not to worry about buffer overflows in Python.

Memory leaks appear in BOTH (specifically, any data structure that accidentally keeps references to stuff will leak memory in python). The biggest difference is that Python won't create the particularly bad/dangerous memory leaks (eg, use after free).
