![]() This means you can define what the + or - operators mean when applied to instances of your own classes. Python allows you to overload operators for your own classes. In this example, the ternary operator checks if x is even or odd, and returns the string "Even" if it’s even, and "Odd" if it’s odd. Print("Even" if x % 2 = 0 else "Odd") # Output: Odd It has the following syntax: value_if_true if condition else value_if_false The ternary operator is a shorthand way of writing an if-else statement in Python. Print(x 3 and x 3 or x 3 and x > 2) # Output: 1 Here are the comparison operators in Python: # Equal to Here are the assignment operators in Python: # Simple assignmentĬomparison operators are used to compare two values and return a Boolean value (True or False). Here are the arithmetic operators in Python: # AdditionĪssignment operators are used to assign values to variables. Arithmetic OperatorsĪrithmetic operators are used to perform mathematical operations such as addition, subtraction, multiplication, division, and modulus. In this blog post, we will explore the different types of operators in Python and provide examples to illustrate their usage. (Data structures).One of the essential features of Python is its operators, which enable you to perform a wide range of operations on data. "Explicit is better than implicit."Īlways remember to explicitly specify the order of precedence in places where it is needed. I would at this point mention one of the most important lines from the zen of python. I could alter the result by using it as such : print 5 * 2 + 10 / 2īoth the above cases would result in a different result. We can however tell the system to execute in a particular fashion by including parenthesis. I hope the need for understanding precedence is clear. Our equation is now as follows : print 15 + 2 next we execute 4 / 2 which results to 2. Let me explain.Īccording to the precedence, first we execute 5 * 3, and the result is 15. The outcome for python however is 17.ĭid you get the same answer ?, Hopefully you did. Would have different results based on the order in which any of these operations are performed. We've taken all the operators we have seen over the past two lessons and arranged them according to the order in which their execution will occur. Let us look at operator precedence so that we understand in what order operations will be performed. We will look at Bitwise operations, Identity operators and Membership operators at a later stage when we complete other comprehensive data structures. When we print b, we see the result as False and for the outcome of print not b, we get the outcome as True. ![]() In the above case you can see we did a comparison operation on a < 3 and assigned the outcome to b. The not operator is the only logical operator that does not take a secondary argument. Hence please not that every comparison operator needs to have both comparing variables irrespective of the logical operator used in between Python also supports 3 major logical operators as shown below: and or notĪ = 5 print a > 3 and a 4 print not a 3 and < 6Īs you notice it would cause a syntax error. ![]() the outcome is not of type string, this outcome is of type bool which can be viewed using a type function in python. ![]() Note however that comparison operators always return a result of either True or False.
