这个问题是关于Python编程语言中的字符串操作的,涉及到字符串的分割方法split()。字符串是由字符组成的序列,可以用单引号或双引号表示。字符串的分割方法split()可以将一个字符串按照指定的分隔符切分成一个列表,列表中的每个元素都是一个子字符串。split()方法有两个可选参数,第一个是分隔符,第二个是最大分割...
s = "PythonString" 1. s.upper(): 这个方法将把字符串`s`中的所有字符转换为大写。 输出结果为: PYTHONSTRING 2. s.lower(): 这个方法将把字符串`s`中的所有字符转换为小写。注意,你的提供的方法中`lower0`是不正确的,我假定你是指`lower()`。 输出结果为: pythonstring 3. s.find('...
