Sep 30, 2008 · Python can now be prevented from writing .pyc or .pyo files by supplying the -B switch to the Python interpreter, or by setting the PYTHONDONTWRITEBYTECODE environment variable before running the interpreter. This setting is available to Python programs as the sys.dont_write_bytecode variable, and Python code can change the value to modify the ...
Jul 13, 2015 · 32. Since your python file is byte compiled you need to run it through the python interpreter. python yourfile.pyc. The reason you can run your .py files directly is because you have the line. #!/usr/bin/python. or. #!/usr/bin/env python. or something similar on the first line in the .py files. This tells your shell to execute the file with the ...
Methods to Avoid .pyc Files. Here are a few methods to prevent the creation of .pyc files: Disable Compilation. Set the environment variable PYTHONDONTWRITEBYTECODE to 1 before running your Python scripts. This will prevent the creation of .pyc files. Use a Virtual Environment.
When Importing a Module: Each time a module is imported into your program, Python checks if the compiled version of the module exists and is valid (i.e., if the .pyc file matches the source code).
Feb 2, 2017 · The fact that you are using a .pyc file means someone made a mistake, not a choice. They should have given you the .py file so that your computer could compile it and run it. A .pyc file is only valid on the exact same OS, architecture, and python version, so we share .py files and let the individual computer compile them. If you really have no ...
