Theif...elsestatement is used to execute a block of code among two alternatives. However, if we need to make a choice between more than two alternatives, we use theif...elif...elsestatement. Syntax ifcondition1:# code block 1elifcondition2:# code block 2else:# code block 3 Let's l...
I think your code won't work: * number from input() * missing closing ) of int() * if is spelt wrong ("If" is not correct) * : in after the if-condition is missing * print() is not indented into the if-block 11th Dec 2021, 8:43 PM Lisa...
if语句用来做判断,并选择要执行的语句分支。基本格式如下: 1 2 3 4 5 6 7 8 9if CONDITION1:code_block(1)elif CONDITION2:code_block(2)elif CONDITION3:...else:code_block_else 其中elif是可选的,可以有任意多个,else是可选的,表示全都不满足条件时该执行的分支。 例如: 1 2 3a = 4ifa > 3...
" thenCat Plus Plus probably gave the most accurate answer– at this point, it would be too destructive to existing code to be practical. But if the question you're really asking is whyelsewas reused in the first place, well, apparently it seemed like a good idea at the time. Persona...
Python relies on indentation (whitespace at the beginning of a line) to define scope in the code. Other programming languages often use curly-brackets for this purpose. Example If statement, without indentation (will raise an error): a =33 ...
If I did punch twice I get your first condition, if I break the 10 mark on damage I get the other. Seems to work. Might want to change dummy=dymmy-3 to dummy=dummy-3 in your last condition. Also, put your comments above or inline with the code it's about to execute not under...
Python当中的判断语句非常简单,并且Python不支持switch,所以即使是多个条件,我们也只能罗列if-else。 # Let's just make a variable some_var = 5 # Here is an if statement. Indentation is significant in Python! # Convention is to use four spaces, not tabs. ...
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; 方法二:Ctrl+N,新建一个,这时直接将代码复制进来,就不会产生这个问题了;直接在IDLE中编译,是每行都要回车的。如...
