In Python, how do I loop through the dictionary and change the value if it equals something?

Question

If the value is None, I\'d like to change it to \"\" (empty string).

I start off like this, but I forget:

for k, v in mydict.items():
    if v is Non         


        

Answer 1

Comprehensions are usually faster, and this has the advantage of not editing mydict during the iteration:

mydict = dict((k, v if v else '') for k, v in mydict.items())
