在Python中,if else语句是一种条件控制语句,它可以根据条件的真假来执行不同的代码块。当有多个条件需要判断时,我们可以使用多个if else语句来实现复杂的逻辑。 基本语法 if else语句的基本语法如下: AI检测代码解析 ifcondition1:# do somethingelifcondition2:# do somethingelse:# do something 1. 2. 3. 4....
Here, the first condition,number > 0, evaluates toFalse. In this scenario, the second condition is checked. The second condition,number < 0, evaluates toTrue. Therefore, the statements inside theelifblock is executed. In the above program, it is important to note that regardless the value o...
You can also have multiple else statements on the same line: Example One line if else statement, with 3 conditions: a =330 b =330 print("A")ifa > belseprint("=")ifa == belseprint("B") Try it Yourself » And Theandkeyword is a logical operator, and is used to combine conditio...
Before Python 3.10, Python developers had to use multiple if-elif-else statements or dictionaries to simulate switch case functionality. Here's a basic exampleusing if-elif-else: day=input("Enter the day of the week: ").capitalize()ifday=="Saturday"orday=="Sunday":print(f"{day}is a we...
由于python3.x系列不再有 raw_input函数,3.x中 input 和从前的 raw_input 等效,把raw_input换成input即可。 SyntaxError: multiple statements found while compiling a single statement 这是因为整体复制过去运行而产生的错误;解决方案如下: 方法一:先将第一行复制,敲一下回车,再将剩下的部分复制过去,运行; ...

Accessing the attribute multiple times creates a method object every time! Therefore o1.method is o1.method is never truthy. Accessing functions as class attributes (as opposed to instance) does not create methods, however; so SomeClass.method is SomeClass.method is truthy.>>> SomeClass....
if x < 0: print('It's negative') elif x == 0: print('Equal to zero') elif 0 < x < 5: print('Positive but smaller than 5') else: print('Positive and larger than or equal to 5') 如果某个条件为True,后面的elif就不会被执行。当使用and和or时,复合条件语句是从左到右执行: ...
