I would use compileall  It works nicely both from scripts and from the command line  It s a bit higher level module tool than the already mentioned py compile that it also uses internally

To match the original question requirements  source path and destination path  the code should be like that   import py compile py compile compile py filepath  pyc filepath    If the input code has errors then the py compile PyCompileError exception is raised

You can use compileall in the terminal  The following command will go recursively into sub directories and make pyc files for all the python files it finds  The compileall module is part of the python standard library  so you don t need to install anything extra to use it  This works exactly the same way for python2 and python3  python -m compileall

There is two way to do this  Command line Using python program  If you are using command line use python -m compileall  lt argument gt  to compile python code to python binary code  Ex  python -m compileall -x     Or  You can use this code to compile your library into byte-code  import compileall import os  lib path    quot your lib path quot  build path    quot your-dest path quot   compileall compile dir lib path  force True  legacy True   def moveToNewLocation cu path       for file in os listdir cu path           if os path isdir os path join cu path  file                compile os path join cu path  file           elif file endswith  quot  pyc quot                dest   os path join build path  cu path  file              os makedirs os path dirname dest   exist ok True              os rename os path join cu path  file   dest   moveToNewLocation lib path   look at   docs python org for detailed documentation

In Python2 you could use  python -m compileall  lt pythonic-project-name gt   which compiles all  py files to  pyc files in a project which contains packages as well as modules   In Python3 you could use  python3 -m compileall  lt pythonic-project-name gt   which compiles all  py files to   pycache   folders in a project which contains packages as well as modules  Or with browning from this post   You can enforce the same layout of  pyc files in the folders as in Python2 by using  python3 -m compileall -b  lt pythonic-project-name gt  The option -b triggers the output of  pyc files to their legacy-locations  i e  the same as in Python2

I found several ways to compile python scripts into bytecode   Using py compile in terminal   python -m py compile File1 py File2 py File3 py       -m specifies the module s  name to be compiled    Or  for interactive compilation of files  python -m py compile - File1 py File2 py File3 py                 Using py compile compile   import py compile py compile compile  YourFileName py    Using py compile main     It compiles several files at a time   import py compile py compile main   File1 py   File2 py   File3 py      The list can grow as long as you wish  Alternatively  you can obviously pass a list of files in main or even file names in command line args   Or  if you pass   -   in main then it can compile files interactively  Using compileall compile dir     import compileall compileall compile dir direname    It compiles every single Python file present in the supplied directory  Using compileall compile file     import compileall compileall compile file  YourFileName py      Take a look at the links below   https   docs python org 3 library py compile html  https   docs python org 3 library compileall html
