I would like to understand what is the difference between the two commands
python main.py and main.py to run the main.py file in the command prompt; and which to use in what circumstance.

main.pyisn't expected to work unless you have.in the PATH, which is a Very Bad Idea for security reasons. It needs to be./main.pyon a better-configured system. (Also, the.pyextension should be present in libraries or modules, not scripts; scripts shouldn't have executables -- same in shell as well)#!/usr/bin/env pythonor another valid shebang, the operating system is charged with starting the executable named in that shebang as an interpreter..inPATHis considered bad practice; Windows systems haven't been multi-user environments for as long and didn't pick up all the hard-learned lessons from the UNIX world's security experience).setup.pythat uses distutils to install your script, and specify your main function as an entry point; it'll automate creating a script to start your program in whatever way is appropriate for the user's operating system (and it'll also make sure any other Python libraries your script needs are installed).
