Python Comparison OperatorsĪ comparison operator, also called python relational operator, compares the values on both sides of the operator to classify the relation between them as either true or false. The above example will print "not equal" as x = 2 as assigned earlier. Also unlike C, expressions like a < b < c have the interpretation that is conventional in mathematics: Comparisons yield boolean values: True or False. The is operator is the object identity operator used to check if two objects in fact are the same and its negation is not : x is y is true if and only if x and y are the same object. Unlike C, all comparison operations in Python have the same priority, which is lower than that of any arithmetic, shifting or bitwise operation. How to Compare Strings Using the < Operator The < operator checks if one string is smaller than the other. I have commented the code to help you understand better. In the example given, a and b have different values. y means the doubled value of the variable x is not equal to the value of the. The is saying the strings are not equal which is False so a message is printed based on those conditions. The does not equal operator (.) can be used to compare two values and determine if they are different. So if the two variables have the same values but they are of different type, then not equal operator will return True. To sum up, the conditional statement in Python has the following syntax. Python is dynamically, but strongly typed, and other statically typed languages would complain about comparing different types. The python != ( not equal operator ) return True, if the values of the two Python operands given on each side of the operator are not equal, otherwise false. (not A) and (not B) is equivalent to not (A or B), and (not A) or (not B) is equivalent to not (A and B). You can use "!=" and "is not" for not equal operation in Python.
