In that case, as x = 10 so it is True. Returns a Boolean stating whether two expressions are not equal.

If values of two operands are not equal, then condition becomes true. The syntax for the "not equal" operator is != in the Python programming language. Not equal in Python is one of the comparison operators. Pythonの非等号(not equal)は<>でも!=でも可。リファレンスマニュアルの推奨は!=。 >>> 1 <> 0 True >>> 1 != 0 True Python リファレンスマニュアル 2.5 演算子 (operator) Description¶. If values of two operands are not equal, then condition becomes true. >. Python not equal operator returns True if two variables are of same type and have different values, if the values are same then it returns False. The expression not x means if x is True or False. The not equal operator is a comparison operator in Python. If the value of left operand is greater than the value of right operand, then condition becomes true. This is similar to != operator. Python is dynamic and strongly typed language, so if the two variables have the same values but they are of different type, then not equal operator will return True .

As x is True, so not operator evaluated as False and else part executed. For comparing object identities, you can use the keyword is, and its negation is not. Using Python not equal.

It can have one of two return values: True means one variable in Python does not equal the other; False means both variables are the same in value Python not equal is an inbuilt operator returns True if two variables are of the same type and have different values, if the values are identical, then it returns False.
In Python, if a variable is a numeric zero or empty, or a None object then it is considered as False, otherwise True. (a <> b) is true. <>.
This operator is most often used in the test condition of an "if" or "while" statement.

The test condition a != b returns false if a is equal to b, or true if a is not equal to b. (a != b) is true.
