How to pass data to the executable script?

Question

linux

I have a python script that asks for some input when run. How can bash transfer this data to it?

Answer 1

Through command line arguments. You can parse either manually or (preferably) with argparse .
An example of how to access the list of given arguments if you still want to parse yourself:

import sys

print(sys.argv)

Answer 2

Call the script with input redirection <<< or <<
For example, to pass a single string:
or for multiple strings:

$ script.py <<_END_
some input string 1
some input string 2
some input string 3
_END_

Well, you can save the data in a file and redirect input from the .
See man bash for REDIRECTION, Here documents, Here strings.

Answer 3

echo "abc" | script.py
