• TheGameiswar: Does this answer your question? Can a python script execute a function inside a bash script?
• Mehul Anshumali: Actually, no because it is directly calling the function I have to pass the argument from python to bash. Thanks BTW.

Answer 1

import subprocess
subprocess.Popen(['bash', '-c', '. bash_script.sh; function_argument2 Please Help'])

To pass input arguments from a list:

inputs = ['Hello', 'How', 'What']
for input_ in inputs:
 subprocess.Popen(['bash', '-c', f'. bash_script.sh; function_argument2 {input_}'])

• Mehul Anshumali: Thank you so much working ... I had spent 1 week to figure out this thing. Thank You so much 😊
• Mehul Anshumali: Hey, i have one doubt lets say i have to repeat this process again and again. so i will the for loop like for i in function_call_list: (function call list is a list of parameters say ['Hello', 'How', 'What']. So when i write the subprocess.Popen(['bash', '-c', '. bash_script.sh; function_argument2 i ']) i value it is not taking. what should i do
