I am using Flask.
I am doing a ajax post and I need to check for existence if keys.
I tried this but did not work.
if request.args.has_key('campaign_id_crid'): print True
What is a better way to test?
Your example works fine (once an
if is added to the start anyway...)
dict.has_key is still about (in existing 2.x code - but removed in Python 3), it's generally considered more Pythonic to use the
in operator such as:
if 'campaign_id_crid' in request.args: pass # do something
