What does "-c" mean in this linux shell command? – Debian

It’s from a tutorial on the google cloud platform, they call python from the Linux Shell.
I’m totally new to gcp and linux, please help me, where can I find some exhaustive documentation for python tools in Linux? 

python -c 'import base64, sys, json; 
  img = base64.b64encode(open(sys.argv[1], "rb").read()); 
  print json.dumps({"key":"1", "image_bytes": {"b64": img}})'

    -c stand for cmd which allows you to pass your code as a string.
