== is an Equal To Operator in C and C++ only, It is Binary Operator which operates on two operands. == compares value of left and side expressions, return 1 if they are equal other will it will return 0.
What is == used for?
The == operator is an equality operator. It checks whether its two operands are the same or not by changing expression from one data type to others. You can use == operator in order to compare the identity of two operands even though, they are not of a similar type.

That is the 'equal to' sign sign. It's called an 'comparison operator'. e..g. text.length == text.length OR text.length == 4 OR 5 + 10 == 15. As far as I know, comparison operators are used with Booleans(True or False data type) to determine whether or not a block of code should run.

It returns mean of the data set passed as parameters. Arithmetic mean is the sum of data divided by the number of data-points. It is a measure of the central location of data in a set of values which vary in range. In Python, we usually do this by dividing the sum of given numbers with the count of number present.
