In C#, I can say x ?? ""
, which will give me x if x is not null, and the empty string if x is null. I've found it useful for working with databases.
Is there a way to return a default value if Python finds None in a variable?
You could use the or
operator:
return x or "default"
Note that this also returns "default"
if x
is any falsy value, including an empty list, 0, empty string, or even datetime.time(0)
(midnight).
Python 3.8+ update: bool(datetime.time(0))
now resolves to True
. This was resolved with issue13936. Other "empty" values are still considered "falsy" as expected.
