Return a lowercased, casefolded string similar tolower()but more aggressive because it removes all case distinctions. For example, the German lowercase letter'ß'is already lowercase and'ß'.lower()wouldn’t change it. But because'ß'is equivalent to'ss',str.casefold()converts'ß'to'...
We’re not changing the underlying string that was assigned to it before. We’re assigning a whole new string with different content. In this case, it was pretty easy to find the index to change as there are few characters in the string.How are we supposed to know which character to ch...
A string containing all characters that are considered whitespace. On most systems this includes the characters space, tab, linefeed, return, formfeed, and vertical tab. Do not change its definition — the effect on the routines strip() and split() is undefined. print string.whitespace 2. st...

这被称为样板代码。例如,在清单 2-4 中,行public static void Main(String args[])和清单 2-5 ,public static void Main( )可能分别被归类为 Java 和 C# 端的样板代码。我们将在后面的章节中详细讨论这个概念。 现在,与 Java 相比,C# 对它的许多函数使用了不同的词汇。为了在屏幕上打印文本,我们有控制...

keeps an array of integer objects for all integers between -5 and 256, when you create an int in that range you actually just get back a reference to the existing object. So it should be possible to change the value of 1. I suspect the behaviour of Python in this case is undefined....
