Python is not equal to how to write

How to express not equal in python?

In Python language, use != to indicate inequality. We understand through the following simple example:

In the above example, variables x and y are assigned values ​​first, and then the if statement is used to determine whether x and y are equal. , if they are not equal, print the value of x y; if they are equal, print the value of x - y. Obviously, x is not equal to y, and the result is the value of x y, which is 17. In the above example, != is the inequality symbol, which is formed by! Used in combination with =.

Another example, as follows

We use Python to verify that 40 is not equal to 40, and the returned result is False, which is wrong ;Verify that 45 is not equal to 48, and the result returns True. Verify that list a and list b are equal. False is also returned because they are not equal!

So far, we have mastered how to express inequality in Python, which is represented by !=. Not only can it determine whether two numbers and lists are equal, it can also verify whether two strings, tuples, dictionaries, or sets are equal!
