Check If The Value Exists In The List Using In Operator

In this article, we will check if the value exists in the list using in operator.

Example

Consider the following example

list = [1,2,3]

print(11 in list)

Here the value ‘11’ does not exist in list so the above expression will print false. Similarly, the following example will return true.

list = [1,2,3]

print(2 in list)

Not In Operator

There is another operator ‘not in’ that python supports. ‘Not in’ operator returns false if the value exist in the list or string or vice versa.

Here is an example

list = [1,2,3]

print(2 not in list)

Once you run the above program, you will get following output
