现实生活中文字随处可见,编程语言中则用字符串来表示,字符串是Python中最常用的数据类型。想想在没有图形化界面的时代,几乎都是对字符串和数字的处理,衍生到后来的网页、Windows应用程序等都能看到对字符串的操作。还有每个国家都有不同的语言,而字符串有不同的字符串编码来表示。越容易小瞧的反而越重要 ...
| suffix can also be a tuple of strings to try. | format(...) | S.format(*args, **kwargs) -> str | | Return a formatted version of S, using substitutions from args and kwargs. | The substitutions are identified by braces ('{' and '}'). | | format_map(...) | S.format...
Python map 函数 相反,让我们使用 Python map 函数来生成最佳结果。我们将从需要转换的字符串列表开始: AI检测代码解析 list_of_strings = ["5", "6", "7", "8", "9", "10"] 1. 然后我们将使用 Python map 函数将字符串列表转换为整数列表: ...

与map很相似,我们也可以用列表推导式来代替filter实现。上述例子我们也写一个列表推导式的版本吧。 过滤数字 >>> list_of_strings = ['one', 'two', 'list', '', 'dict', '100', '1', '50'] >>> [s for s in list_of_strings if s.isdigit()] ['100', '1', '50'] >>> 过滤奇偶 ...
