You can use dict.get()
here:
if name_dict.get(name):
info = name_dict['name']
else:
info = input("Input your info: ")
name_dict.get(name)
will only be true if name
exists as a key in name_dict
, and the value associated with the key is not an empty value (''
is false in a boolean context, if name
is missing None
is returned, which is also a false value).
These two lines can be combined with or
, eliminating the if
statement altogether:
info = name_dict.get(name) or input("Input your info: ")
That’s because or
short-circuits. If name_dict.get(name)
produces a non-empty value, the input()
function will not be called.
