i working in python, , using dict
in code.
i have case need default
value if give key
not exist or if key
exists , has falsy
value.
for example
x = {'a': 'test', 'b': false, 'c': none, 'd': ''} print x.get('a', []) test print x.get('b', []) # need [] false falsy value in python false print x.get('e', []) # work fine, because `e` not valid key none print x.get('c', []) none print x.get('c', []) or [] # gives output want
instead of check falsy
value in or
operation, there pythonic way default value?
using or
return default value pythonic. i'm not sure more readable workaround.
about using or
in docs:
this short-circuit operator, evaluates second argument if first 1 false.
you must consider value must have been accessed first before can evaluated falsy or truthy.
