Output:In this Python string, the hyphen is at the5th position(remember, Python uses 0-based indexing). To remove the hyphen, we can take all characters before it and all characters after it, then concatenate them together. By concatenating these two substrings, we effectively remove the hyph...

处理字符串的一个常用标准库模块是string。在string 模块中,你可以使用多个函数来有效管理字符串。 1)split函数 使用split 函数来将一个字符串拆分成一个子字符串列表,列表中的子字符串正好可以构成原字符串。(列表是Python 中的另一种内置数据类型) split 函数可以在括号中使用两个附加参数。第一个附加参数表示使...
