Python 中的“in”和“==”

Question

What's the difference in the usage of in and == in python ? I want to explore more while comparing with a single character .

if gender in "M":
    print "Male"

if gender == "M":
    print "Male"

Of the following, which one can be more beneficial to use, in or == ?

Answer 1

in your case there is no need to use in, since you are comparing one character.

use ==

Answer 2

当您使用“in”时，它表示列表中的一个对象（“money”表示 m、o、n、e、y 中的任何一个）但 == 表示整笔钱。

Answer 3

Use == :

>>> "" in "M"
True
