In Python, it is possible to write multiple if statements on one line. This allows you to create a concise and compact code structure to handle multiple conditions.But first, we will see how to write an if-elif-else in separate lines, like in the following example.Example Code:...
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...

总结一下,鉴于类似序列的数据结构的重要性,Python 通过在 __iter__ 和__contains__ 不可用时调用 __getitem__ 来使迭代和 in 运算符正常工作。第一章中的原始FrenchDeck也没有继承abc.Sequence,但它实现了序列协议的两种方法:__getitem__和__len__。参见示例 13-2。
