@propertydef string(self):return "".join((str(c) for c in self.characters)) 这段代码使用了一个生成器表达式,我们将在第二十一章中讨论,迭代器模式。这是一个在序列中对所有对象执行特定操作的快捷方式。 最后,我们还需要检查home和end函数中的Character.character,而不仅仅是我们之前存储的字符串字符,看...
The left edge of the first character in the string is numbered 0. We can slice from this location with the index i. The right edge of the last character of a string of n characters has the index n. We can slice from this location with the index j. For example:Python Copy ...
3.SyntaxError: invalid character ')' (U+FF09) 一般是在语句中使用了中文输入的符号,比如括号,逗号,冒号,单引号,双引号等。 Python里面这些字符就是非法的,需要在英文状态下输入。 s = 0 for i in range(1, 6): s = s + i print( s) # 此处右括号是在中文状态输入的 ...
