Execute shell command and use it's output in Jupyter

Question

I know this is a recurrent question, but I can't find a useful answer.

In Python, for running a shell command one can use this.

If I do the same inside Jupyter I got no output. How can I see the results of executing the command? Doing

print subprocess.call(["ping", "-c 2", "www.cyberciti.biz"])

returns zero.

Running shell commands requires access to the OS running the Python script. Scripts in Jupyter are probably denied that access for security reasons. — Harry Cutts

Use the ! shell magic:

!ping -c 2 www.cyberciti.biz

If you want to assign it to a variable:

output = !ping -c 2 www.cyberciti.biz
print(output)
