4.5. Standard Type Operators

4.5.1. Value Comparison

Comparison operators are used to determine equality of two data values between members of the same type. These comparison operators are supported for all built-in types. Comparisons yield true or false values, based on the validity of the comparison expression. Python chooses to interpret these values as the plain integers 0 and 1 for false and true, respectively, meaning that each comparison will result in one of those two possible values. A list of Python's value comparison operators is given in Table 4.1.

Table 4.1. Standard Type Value Comparison Operators

operator	function
expr1 < expr2	expr1 is less than expr2
expr1 > expr2	expr1 is greater than expr2
expr1 <= expr2	expr1 is less than or equal to expr2
expr1 >= expr2	expr1 is greater than or equal to expr2
expr1 == expr2	expr1 is equal to expr2
expr1 != expr2	expr1 is not equal to expr2 (C-style)
expr1 <> expr2	expr1 is not equal to expr2 (ABC/Pascal-style)[a]

^[a] This “not equals” sign will slowly be phased out. Use != instead.
