To perform more complex checks, if statements can be nested, one inside the other. This means that the inner if statement is the statement part of the outer one. This is one way to see whether multiple condition
在if语句中,只有缩进相同的代码块才被视为同一个代码块。通常情况下,Python推荐使用四个空格作为一个缩进级别,而不要使用制表符。 下面是一个使用if语句的示例,演示了缩进的规则: x=10ifx>5:print("x is greater than 5")print("This statement is also inside the if block")print("This statement is ou...

The “OR” operator in Python “if statement” is used to combine multiple conditions and filter out the information based on the specified conditions.
Python Copy In this example, we first import theosmodule. We then define a variablefile_paththat holds the name of the file we want to check. We pass this variable to theos.path.exists()function inside anifstatement. If the file exists, it prints ‘The file exists!’, and if it doesn...
IF Statement is one of the popular Excel instructions that can be used as a decision-making statement. It is one of the foundational programming concepts
Example of multiple lines inside if statement It is perfectly fine to have more lines inside theifstatement, as shown in the below example. The script will return two lines when you run it. If the condition is not passed, the expression is not executed. ...
