Can anyone tell me how to set the output of a command to a variable?

Basically, I'm looking for the Python equivalent to this bash example: 

blah="ajsdlk akajl <ajksd@ajksldf.com>"
blah=$(echo "$blah" | cut -d '<' -f 2 | cut -d '>' -f 1)
echo "$blah"
ajksd@ajksldf.com

  • You can use subprocess. This looks very close to http://stackoverflow.com/questions/4760215/running-shell-command-from-python-and-capturing-the-output –  Aug 30 '15 at 06:06

You may use string.split

>>> blah="ajsdlk akajl <ajksd@ajksldf.com>"
>>> blah.split('<')[1].split('>')[0]
'ajksd@ajksldf.com'

If a function returns a string, just capture its return value. If you're looking to capture the standard output from a function, wrap it with a StringIO wrapper.
