'How to insert a python program into a bash script?

I have a small python program that parses a text file and writes the output to another file. Currently, I am writing a bash script to call this program several times, it looks something like:

for i in $(seq 1 100); do

          python /home/Documents/myProgram.py myTextFile$i

done

This works fine but I want to know if it is possible to have the python program inside the bash script file so when another user runs the script they don't need to have the python program in their memory; i.e., is it possible to copy and paste the python program into the bash script and run it from within the script itself?

I think you should be able to put:

python  << END
[Python code here]
END

But I have not tested this.

Solution 2:[2]

for simple scripts you can also run python with the -c option. For example

python -c "x=1; print x; print 'great program eh'"

I wouldn't recommend writing anything too complicated, but it could work for something simple.

Pardon the thread necromancy, but here's a technique that is missing that may be useful to someone.

#!/bin/bash
""":" # Hide bash from python
for i in $(seq 1 100); do
  python3 $(readlink -f "$0") myTextFile$i
done
exit
"""
# Python script starts here
import sys
print('Argument List: ', str(sys.argv))

However, I do agree with the general recommendation to just do the loop in Python.
