Here's the trick to using python as a one liner: sys.stdin.read()
quick example
echo "zero one two three" | python -c 'import sys; print(sys.stdin.read().split(" ")[2])
Above, we print sample output and pipe it to a python program..
The Python takes everything from stdin and reads it into a string, turns it into a list by splitting at spaces, and prints the third item in the list.
parsing json
To parse json, use -m json.tool:
$ curl "https://git.charlesreid1.com/api/v1/user/repos?access_token=a936efc887b1947561ab901d08abe3b3b3128a80" | python -m json.tool
