How to call Bash Script function from Python Script

Question

Suppose I have two functions function_arguments1 and function_agruments2 which are accepting parameters. I want to call the function name:- function_argument1, from python script. How should I call the function_arguments1 from Python passing parameters from python script.

#!/bin/bash  
#Script to pass and access arguments  
  
function_arguments1(){  
    echo $1  
    echo $2  
    echo $3  
    echo $4  
    echo $5  
}  
  

function_argument2(){
    echo $1  
    echo $2  
}

#Calling function_arguments2  
function_arguments2 "Please""Help"

Does this answer your question? Can a python script execute a function inside a bash script? — TheGameiswar

Actually, no because it is directly calling the function I have to pass the argument from python to bash. Thanks BTW. — Mehul Anshumali

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_}'])

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
