【python】python 一行 if else 語法 (one line if else) sample code (內含範例程式碼) 前言這個算是比較fancy的功能,有時為了排版漂亮、或邏輯已經很簡單,不需要撰寫多行程式碼時,才會使用。Sample Code 使用方法
在Java和C语言中用花括号{}包起来的部分就是一个代码块,shell脚本中的代码块是由专门的开始和结束标识的,而python中的代码块是靠“缩进对齐”来表示的。下面我们分别一个if-else的条件判断来对这几个语言的代码块表示方式做一个对比: 1. Java 代码语言:javascript 代码运行次数:0...
Python3基础条件控制 if ---elif---else Python3 条件控制 Python条件语句是通过一条或多条语句的执行结果(True或者False)来决定执行的代码块。 可以通过下图来简单了解条件语句的执行过程: if 语句 Python中if语句的一般形式如下所示: if condition_1: statement_block_1elif condition_2: statement_block_2else...
# If-Elif-Else statement on one line in Python Use a nested ternary operator to implement an if-elif-else statement on one line. The first ternary should check for a condition and if the condition is not met, it should return another ternary that does the job of an elif/else statement...
The syntax for if-else in one line in Python To use the if-else in one line in Python, we can use the expression: a if condition else b. In this expression, a is evaluated if the condition is True. If the condition is false, then b is evaluated. Let us use this as an example...
A statement block is a sequence of one or more statements executed after the conditions are met, and the statements in the statement block express the containment relationship by indenting the line where the if is located. The if statement first evaluates the result value of the condition, and ...
The eval function works only with simple expressions.Expressions that are split over more than one line (such as if statements) generally won’t evaluate Since user input is read in as a string, Python needs to convert it into numbers and operators before doing any calculations. exec The ex...
Write an if-else in a single line of code You can write an if-else statement in one line using a ternary expression. This can make the code more concise. #create a integer n = 150 print(n) #if n is greater than 500, n is multiplied by 7, otherwise n is divided by 7 ...
