WebWhile pure Python scripts can be compiled with Cython, it usually results only in a speed gain of about 20%-50%. To go beyond that, Cython provides language constructs to add static typing and cythonic functionalities to a Python module to make it run much faster when compiled, while still allowing it to be interpreted. WebFor example, to test at C compilation time which CPython version your code is being compiled with, you can do this: Pure Python Cython py_version_hex.py ¶ from cython.cimports.cpython.version import PY_VERSION_HEX # Python version >= 3.2 final ? print(PY_VERSION_HEX >= 0x030200F0) Cython also provides declarations for the C …
