在Python 编程中,二元判断式(又称三元操作符)是一种简洁的条件表达式,它提供了一个简练的方式来根据条件选择值。它的语法形如x if condition else y,意味着如果condition为 True,则返回x,否则返回y。 二元判断式的基本用法 二元判断式的主要优点是可读性与简洁性。在某些情况下,使用二元判断式可以将代码简化,减少...
简介:Python系列(13)—— 三元运算符 在Python中,三元运算符(Ternary Operator)是一种简洁的条件表达式,它允许我们在一行代码中执行简单的条件判断。三元运算符的格式如下: value_if_true if condition else value_if_false 如果condition为True,则整个表达式的值为value_if_true;如果condition为False,则整个表达式的...
1.三元操作符(Ternary operator) 三元操作符是if-else语句的简写形式。其语法为value_if_true if condition else value_if_false。这是一个一行的代码,可以替代多行的if-else语句,使你的代码更加简洁: a = 5 b = 10 max = a if a > b else b ## value_if_true if condition else value_if_false ...
In cases when users want to adddecision-making statements, they can use this ternary operator. It is better to use this operator compared to using longer conditional statements like if and else in some cases. Thus, using this conditional operator, users can simplytest a condition in a single ...

ternary.py#!/usr/bin/python # ternary.py age = 31 adult = True if age >= 18 else False print("Adult: {0}".format(adult)) In many countries the adulthood is based on your age. You are adult if you are older than a certain age. This is a situation for a ternary operator. ...

1. Syntax of Python Ternary Operator The syntax of the ternary operator. # Syntax of ternary operator value_if_true if condition else value_if_false In this syntax,conditionis a statement that can be eitherTrueorFalse. If the condition isTrue, the value ofvalue_if_truewill be returned. If...
Another reason to avoid using a tupled ternery is that it results in both elements of the tuple being evaluated, whereas the if-else ternary operator does not. Example: condition=Trueprint(2ifconditionelse1/0)#Output is 2print((1/0,2)[condition])#ZeroDivisionError is raised ...
The ternary operator, also known as the conditional expression, provides a concise way to write simple conditional statements in Python. It is often used to assign a value to a variable based on a condition, all in a single line of code. The syntax for the ternary operator is value_if_...
