Python - json without whitespaces

Question

I just realized that json.dumps() adds spaces in the JSON object

e.g.

{'duration': '02:55', 'name': 'flower', 'chg': 0} 

how can remove the spaces in order to make the JSON more compact and save bytes to be sent via HTTP?

such as:

{'duration':'02:55','name':'flower','chg':0} 

Answer 1

json.dumps(separators=(',', ':'))
