在python中调用函数时出错“函数未定义”

Question

我面临这个错误，我的函数被说成是没有定义的尽管我已经正确定义并调用函数，这是我得到的错误，请帮助：

文件“split_text.py”，行80，在 split_pun（字）#passing词的价值split_pun函数删除标点但是这给了我一个错误 NameError：名字“split_pun”没有定义

这里是代码：

Answer 1

由于split_pun是UrduCorpusReader类中的实例方法，因此需要从实例中调用它。

split_pun(word)应该是wordlists.split_pun(word)
（就像您使用wordlists.words(infile)上面的线一样）。
