将if-else语句转换为单行的方法

Question

有没有办法在一行上执行以下操作？

if completion.is_anonymous:
    user = 'Anonymous'
else:
    user = completion.user

Answer 1

使用三元运算符：

user = 'Anonymous' if completion.is_anonymous else completion.user

Answer 2

有user = "Anonymous" if completion.is_anonymous else completion.user语法：

>>> a = 2 if True else 4
>>> a
2
>>> a = 2 if False else 4
>>> a
4
