猜测 There should be one-- and preferably only one --obvious way to do it. # 而是尽量找一种,最好是唯一一种明显的解决方案(如果不确定,就用穷举法) Although that way may not be obvious at first unless you're Dutch. # 虽然这并不容易,因为你不是 Python 之父(这里的Dutch是指Guido) Now is...
但是,如果你确实遇到了SyntaxError: multiple statements on one line (and no semicolon to separate them)这个错误,那通常意味着你可能有以下几种情况之一: 在一行中写了多个独立的语句,并且没有用分号分隔它们,但你的环境或工具错误地报告了这个错误。这通常不应该发生,因为 Python 通常会忽略没有分号的多个语句...

Python中if语句的一般形式如下所示: ifcondition_1: statement_block_1 elifcondition_2: statement_block_2 else: statement_block_3 l如果 "condition_1" 为 True 将执行 "statement_block_1" 块语句 l如果 "condition_1" 为False,将判断 "condition_2" ...
The if statement in the above code ensures that something is implemented if and only if the entirecondition_listis true. Otherwise, something else is implemented when even one of the conditions in thecondition_listis false. We encountered theDoing something else.as output since the condition in...

Compact if Statement In certain situations, the if statement can be simplified into a single line. For example, number = 10 if number > 0: print('Positive') Run Code This code can be compactly written as number = 10 if number > 0: print('Positive') Run Code This one-liner approach...
