I am using Flask.
I am doing an ajax post and I need to check for the existence of a key
I tried the following, but it didn’t work
if request.args.has_key('campaign_id_crid'): print True
What would be the right way to do that?
Your example works fine in python 2.x code
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
