Python 中 if 语句中的多行条件在 PEP8 中提供了各种允许的方式。 首先,不应将多个条件语句放在一行中。相反,将多条件的这一行拆分并将它们括在括号中。 # do not define the multiple conditions in a single line like this if ( firstcondition == "something" and secondcondition == "something else" ...
实际上,你可以使用分号来分隔它们,但这并不常见,也不推荐,因为 Python 的代码风格(PEP 8)鼓励一行只写一个语句以提高可读性。 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...

One Line for Loop in Python Using List Comprehension with if-else Statement The “If else” with “List comprehension” creates more powerful operations like saving space or fast processing repetitive programs. We can perform multiple operations using a single line for loop conditions of list compre...
A statement block is a sequence of one or more statements executed after the conditions are met, and the statements in the statement block express the containment relationship by indenting the line where the if is located. The if statement first evaluates the result value of the condition, and ...
