I recently started python development on raspberry pi. While reading about .pyc file to speed up the start up, I was wondering if I test a .pyc file on PC, given that same python modules are available on Rpi, will it work directly ? Please also include what happens if python version or any of module version differs on target platform.
Thanks in advance.

pyc" file is platform independent, so a Python module directory can be shared by machines of different architectures. Some tips for experts: When the Python interpreter is invoked with the -O flag, optimized code is generated and stored in ". pyo" files.
. py files contain the source code of a program. Whereas, . pyc file contains the bytecode of your program.
pyc files is faster than parsing the . py file using ANTLR.
pyc file contains the “compiled bytecode” of the imported module/program so that the “translation” from source code to bytecode can be skipped on subsequent imports of the *. py file. Having a *. pyc file saves the compilation time of converting the python source code to byte code, every time the file is imported.
Compiled Python bytecode files are architecture-independent, but VM-dependent. A .pyc file will only work on a specific set of Python versions determined by the magic number stored in the file.
