We can access a module, variables, files from a subdirectory using two different functions. Weband you want a program to automatically pick up every module which is located in this subdirectory and process it in a certain way you could achieve it as follows: import glob. This is the efficient method in python. The following Regardless, one way to deal with this is to add the package as a subdirectory in your own project. importlib.resources provides routines for accessing non-code get_tag(); if sys.implementation.cache_tag is not defined then importlib.abc.InspectLoader.get_source()). sys.ps1 and sys.ps2 define the strings used as primary and secondary Web47 6 thatphanom.techno@gmail.com 042-532028 , 042-532027 Now I am going to write a code for main.py.
