在Python中,我们使用 Elif 语句基于提供的条件做另一项决策。elif 语句必须结合 if 语句使用,意味着你不能脱离 if 去单独创建一个 elif 语句。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...
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...

In the above case Python evaluates each expression (i.e. the condition) one by one and if a true condition is found the statement(s) block under that expression will be executed. If no true condition is found the statement(s) block under else will be executed. In the following example,...
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 Kopírovať a = 27 b = 93 if a <= b: print("a is less than or equal to b") elif a == b: print("a is equal to b") Output: a is less than or equal to bIn this variation, the elif statement in the block of code won't run, because the if statement ...
I don't understand why this always evaluate only the first elif statement as true, this even when it should be evaluated as false and go to the next statement. I'm usingPython3https://code.sololearn.com/clMh2gy56Plq/?ref=app
您可以在一开始就将输入转换为int(不需要在每个if中都转换): age = int(input('What year where you born? ')) 将==符号替换为in。 elif age in range(1981, 2000): ... Python中有一个约定:变量名应以smaller-case字母开头。 如果执行了多个(和运算符)函数,请执行某些操作 ...
Python小助手 elif 是Python(以及其他一些编程语言,如C、C++、Java等)中的一个关键字,它是 "else if" 的缩写。它用于在条件语句(如 if 语句)中检查多个条件。 当一个 if 语句后面跟着一个或多个 elif 语句时,Python 会按顺序检查每个条件。如果 if 语句的条件不满足,Python 会继续检查第一个 elif 语句的...
