Python’s development team chose defaults that reflect the most common real-world scenarios. But if you do need to tweak the way garbage collection works, you can use Python’s gc module .

This is a regular Python program that will call the integrate_f function found in num.pyx. Python code “sees” compiled Cython code as just another module, so you don’t need to do anything ...

Devs unknowingly use “malicious” modules snuck into official Python repository Code packages available in PyPI contained modified installation scripts.

Therefore, almost all of the functions that you'll deal with when interacting with the Python interpreter will take or return pointers to PyObjects rather than another more specific Python data type.
