python subprocess output without

Question

Here is a simple script running subprocess that retrieves IP from the ifconfig command output from the terminal. I have noticed that subprocess.check_output() always returns a value with .

I desire to get a return value without . How can this be done?

$ python
>>> import subprocess
>>> subprocess.check_output("ifconfig en0 | awk '{ print $2}' | grep -E -o '([0-9]{1,3}[.]){3}[0-9]{1,3}'", shell=True)
'129.194.246.245
'

Answer 1

For a generic way :

subprocess.check_output("echo hello world", shell=True).strip()
