run python file from python shell code example

Example 1: execute command in python script

import os

os.system("ma Commande")

#Exemple:

os.system("cd Documents")

Example 2: executing shell commands from python script

import subprocess
subprocess.run(["bash", "testShell.sh"])
#we don't have to give full path to the shell script. It always execute from the current directory

#As a rule of thumb, you need to separate the arguments based on space, 
#for example ls -alh would be ["ls", "-alh"], while ls -a -l -h, 
#would be ["ls", "-a", -"l", "-h"]. As another example, 
#echo hello world would be ["echo", "hello", "world"], 
#whereas echo "hello world" or echo hello\ world would 
#be ["echo", "hello world"].

#Another example.
list_files = subprocess.run(["ls", "-l"])
print("The exit code was: %d" % list_files.returncode)

Example 3: how to run a python script

# Save the script in a file with .py extension
# run the script using the below command
python fileName.py

Example 4: run python program from command line

# press [windows] + [R] (on windows only)
# use the command : cd/the_way_of_your_program
# and now use this command :

py the_name_of_your_program.py 

# don't forget to write the extension (py for python) 
# at the end of your program name
