how to run bash script in python

import os

os.system("ma Commande")

#Exemple:

os.system("cd Documents")

import subprocess
print "start"
subprocess.call("sleep.sh")
print "end"

You can use heredoc if you want to keep the source of both bash and python scripts together. For example, say the following are the contents of a file called pyinbash.sh:

#!/bin/bash

echo "Executing a bash statement"
export bashvar=100

cat << EOF > pyscript.py
#!/usr/bin/python
import subprocess

print 'Hello python'
subprocess.call(["echo","$bashvar"])

EOF

chmod 755 pyscript.py

./pyscript.py
Now running the pyinbash.sh will yield:

$ chmod 755 pyinbash.sh
$ ./pyinbash.sh
Exe

#!/bin/bash
python3
print("Hello World")
exit()
echo "The execution is completed"

#!/bin/bash

PYCMD=$(cat <<EOF
from datetime import datetime

first_day_of_new_year = datetime(2022, 1, 1)

days_remaining = (first_day_of_new_year - datetime.now()).days
print('{} days remaining in this year'.format(days_remaining))
EOF
)

python3 -c "$PYCMD"
