Python 由上到下处理代码,所以它先处理 if 语句,如果 if 语句不成立,它再继续处理第一个 elif 语句去检查它的条件。如果条件仍然不成立,python继续执行下个一条件语句直到所有条件语句都检查完毕。然后,一旦有一个条件语句成立,其他所有的条件语句都会被跳过,即使它们的条件成立。它运行的机制是只在第一个成立的...

The if-elif-else statement in Python is used to conditionally execute a statement or a block of statements. It helps control the flow of execution based on different conditions, evaluating expressions as either true or false. Key points: ...
Python中的if和elif语句是控制流语句，用于根据条件执行不同的代码块。if语句用于检查一个条件是否为真，如果为真，则执行一个代码块。elif语句也是用于检查条件，但是只有在前面的if语句不成立时才会执行。一、if语句 1.基本用法 if语句的基本格式如下：```if condition:statement(s)```其中condition是要检查的...
Python中的for循环可以作为函数中的elif语句的一部分。elif是if语句的一种扩展,用于在多个条件中选择执行特定的代码块。 在函数中,elif语句可以用于根据不同的条件执行不同的代码块。当...
python if-statement 我正在学习python,我对if语句有疑问。我收到一个字符串形式的输入,要求你猜测输出句子中的单词/字符。我试图为它得到两个不同的输出。一个输出是“字符x出现/不出现在输出句子中”,另一个是“单词x出现/没有出现在输出语句中”。我设置了一个变量来检查输入的长度,并决定它是字符还是单词...
