Question

我正在使用turtle作为GUI编写单词预测程序，但我无法使代码生效。我的问题涉及WordList类和该类中的readlist方法（接近代码的末尾）。这是我收到的错误消息：

Traceback (most recent call last):
File "C:\Python32\Projects\Practice 3.py", line 118, in <module>
main()
File "C:\Python32\Projects\Practice 3.py", line 115, in main
wordlist = WordList(alpha,'greatexpectationschapter1.txt')
File "C:\Python32\Projects\Practice 3.py", line 89, in __init__
self.list = self.stripchar()
TypeError: stripchar() takes exactly 2 arguments (1 given)

我能做些什么来解决它吗？谢谢你的帮助。

在这一行

self.list = self.stripchar()

你必须明确告诉必须剥离哪个字符串。这很可能是

self.list = self.stripchar(self.list)

这两行可以简单地写成

self.list = self.stripchar(self.readlist(doc))

Python龟类和方法：TypeError：'method'需要2个参数（给定1个）？
