- Create a conditional expression.
Conditional expressions
A conditional expression (also known as a "ternary operator") is a simplified, single-line version of an if-else statement.
Conditional expression template:
expression_if_true if condition else expression_if_false
A conditional expression is evaluated by first checking the condition. If condition is true, expression_if_true is evaluated, and the result is the resulting value of the conditional expression. Else, expression_if_false is evaluated, and the result is the resulting value of the conditional expression.
A variable can be assigned with a conditional expression. Ex: Finding the max of two numbers can be calculated with max_num = y if x < y else x
Note: Conditional expressions have the lowest precedence of all Python operations.
response = "odd" if x%2 == 0 else "even"response = "even" if x%2 == 0 else "odd"Write a program that reads in an integer, ping, and prints ping_report, a string indicating whether the ping is low to average or too high. ping values under 150 have a ping_report of "low to average". ping values of 150 and higher have a ping_report of "too high". Use a conditional expression to assign ping_report.
Ex: If the input is 30, the output is "Ping is low to average".
