Python sys.argv and argparse

Question

I was looking for ways to add argument values ​​to a script when I run it from the command line. Two packages found that seem to do this are sys.argv and argparse.

I would also like to add some help function if possible.

Can someone explain the difference between the two, and maybe it will be easier for someone to start?

Answer 1

sys.argv is just a list of command line arguments.

argparse- A full-featured command line parser that typically parses sys.argvand returns data much easier to use.
