∟__pycache__/module.version.pyc Files

This section provides a quick introduction to the __pycache__/module.version.pyc file. which is a binary file created by the Python system to store the compiled version of the given module file.

What Is a __pycache__/module.version.pyc File? A __pycache__/module.version.pyc file is a binary file created by the Python system to store the compiled version of the given module file.

The Python system uses the __pycache__/module.version.pyc file to avoid compiling the same module file again, if the same module file is requested to be loaded again the next time.

Here is an example of a __pycache__/module.version.pyc file left after the execution of the "import module_test" statement.

herong$ python

>>> import module_test
Hi there! - from 'module_test' module
Welcome on board! - from 'first' class

>>> module_test.version
"1.00 - from 'version' attribute"

>>> exit()

herong$ tree .
    module_test.py
    __pycache__/
          module_test.cpython-38.pyc

Don't worry, if you have accidentally deleted the __pycache__/module.version.pyc file. The Python system will create it again, when the module file is loaded again.
