Conditional statements are a fundamental part of programming, allowing code to make decisions based on certain conditions. In Python, theif/else statementhelps control the execution flow by running different blocks of code depending on whether a condition is met or not. This Basic Syntax ifconditio...
Here, we haven't used indentation after theifstatement. In this case, Python thinks ourifstatement is empty, which results in an error. Python if...else Statement Anifstatement can have an optionalelseclause. Theelsestatement executes if the condition in theifstatement evaluates toFalse. Syntax...
(1) Python if statement) It is one of the most common conditional statements in which some conditions are provided and if the condition is true then block under the if the condition will be executed. 它是最常见的条件语句之一,其中提供了一些条件,如果条件为true,则在条件将被执行时阻塞。 Syntax...
Theif __name__ == ‘__main__’conditional statement is aPython programmingconstruct that controls the execution of a script. When a Python script is run, the interpreter sets thename variableto the string ‘__main__‘ if the script is the main program being executed. If the file is be...
In this step-by-step course you'll learn how to work with conditional ("if") statements in Python. Master if-statements step-by-step and see how to write complex decision making code in your programs.
Python条件控制语句 Python中的条件控制语句 (Conditional control statement)是通过一条或者多条语句的执行结果(True 或者 False),来决定执行的代码逻辑 。 关键词:它包含if、elif、else关键字, Python 中是不存在else if的写法,只存在 elif 这种写法。
IF语句肯定是进行判断,为真怎样,为假如何。 那这个真假就是某个条件是否满足,和Python相关的条件都有哪些呢? 那我们开始进行这些逻辑语句的测试和应用! 一、IF相等与不等 先复习一下上周循环打印列表的功能! 假如我们加个判断,如果名字是桃子的时候,多加个“我爱你”三个字 ...

Here's an example of a nested "if" statement in Python: num = 5 if num > 0: if num % 2 == 0: print("The number is positive and even.") else: print("The number is positive and odd.") else: print("The number is negative.") ...
