I recently decided to learn Python from scratch and already encountered an issue that's hard to solve or find a decent answer to solve it. To be precise, it regards the '[Ernno 2] No such file or directory' error that pops up all the time i try to open any .py file i make. Ive been trying to add a new system path in Environment Variables tab in Windows 10, and apply the same one to python via import os, os.chdir() command. In addition, whenever i change the directory path, it returns to a previous one anytime i reopen the cmd. Just to clarify, i'm completely new to programming , so i'd appreciate any help to this problem .
