In computer programming, we use the if statement to run a block of code only when a specific condition is met. In this tutorial, we will learn about Python if...else statements with the help of examples.
The Python if..else statement executes a block of code, if a specified condition holds true. If the condition is false, another route can be taken.
if .. elif .. else statement When there are multiple conditions to check, you can use the elif clause (short for "else if"). Python evaluates each condition one by one until it finds one that is True. If none are True, the else block is executed. Syntax: if expression1 : statement...
除了基础的单一if结构,许多编程语言支持更复杂的条件逻辑判断,包括if-else语句、else if链以及嵌套的if语句。 IF-ELSE STATEMENT if-else语句提供了当条件不成立时执行代码的能力: if (condition) { // Code to execute if condition is true } else { // Code to execute if condition is false } 在这个结...
if (test_expression) { # body of if statement } else { # body of else statement } The if statement evaluates the test_expression inside the parentheses. If the test_expression is True, body of if is executed body of else is skipped If the test_expression is False body of else is exe...
else写在一行 python 中的if python中if else语句一行,语句:statement 语句是由一些表达式组成的通常一条语句可以独立的执行来完成一部分事情并形成结果 一条语句建议写在一行内 多条语句写在一行内需要用(;)分开 示例:x=10
if-else condition if-elif-else condition if…elif…elseare conditional statements used inPythonthat help you to automatically execute different code based on a particular condition. This tutorial explains each statement in this Python construct, along with examples. ...
else: print('Python Guide') In the above code: The integer value “45” is initialized. The “if” statement is utilized with the combination of the “OR” operator to compare the compound condition. The “OR” operator returns a true Boolean value if any operand conditions become true. ...
3. List Comprehension using If-else We use anif-elsestatement within a list comprehension expression. This allows us to choose between two possible outcomes for each item in the iterable. It’s a useful feature for cases where we need to apply different transformations or labels to the element...
The else statement specifies the block that is executed if the if condition fails. $ go run main.go The number is negative Next we add additional branch with if else. main.go package main import ( "fmt" "math/rand" ) func main() { num := -5 + rand.Intn(10) if num > 0 { ...
