Module Loading
On "import spam", the interpreter looks for the following files:
- spam.so, spammodule.so, spammodule.sl, or spammodule.dll (compiled extensions)
- spam.pyo (optimized bytecode, only with -O option)
- spam.pyc (bytecode)
- spam.py (source)
Creation of .pyc and .pyo files
- Created automatically by the interpreter on module import
- Contain compiled byte-code for the module.
- .pyo files are optimized in the sense that they do not contain
debugging information.
- Regenerated if the modification date of the matching .py file is newer.
- For distribution, only the .pyc or .pyo files are needed (the .py file can
be omitted).
