Pretty print json in python

bgstack15

Comments

For python2 I wanted to show what variables are in use in a function, and I wanted to see it in a nicer format than a really long, single line.

import inspect, json
def function():
print json.dumps(locals(),indent=3,separators=(',',': '))

Bonus

To view what parameters were passed in to a function, add these.

def caller_args():
   frame = inspect.currentframe()
   outer_frames = inspect.getouterframes(frame)
   caller_frame = outer_frames[1][0]
   return inspect.getargvalues(caller_frame)

def function():
print caller_args()
