您将定义一个名为YString. 此数据类型基于内置字符串类,但类型对象YString赋予字母 Y 比所有其他字母更重要: 深色代码主题 复制 # ystring.pyclassYString(str):def__init__(self, text):super().__init__()def__str__(self):"""Display string as lowercase except for Ys that are uppercase"""retu...
您可以在autbor.com/convertlowercase查看该程序的执行情况。如果字符串至少有一个字母并且所有字母都是大写或小写,那么isupper()和islower()方法将返回一个布尔值True。否则,该方法返回False。在交互式 Shell 中输入以下内容,并注意每个方法调用返回的内容:

So Python returns a new string to me. 我也可以使用负索引进行切片。 I can also do slicing using negative indices. 例如,如果我键入S,减去3,Python将给出该序列中的最后三个字符,即h、o和n。 So for example, if I type S, minus 3, Python will give me the last three characters in that sequ...
A Python String object is immutable, so you can’t change its value. Any method that manipulates a string value returns a new String object. The examples in this tutorial use thePython interactive consolein the command line to demonstrate different methods that remove characters. ...
