call shell script from python

1import subprocess
2subprocess.run(["bash", "testShell.sh"])
3#we don't have to give full path to the shell script. It always execute from the current directory

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

12#Another example.
