Question

我正面临这个错误，我的功能据说没有定义即使我已经正确定义并调用了函数，这是我得到的错误请帮助：

文件＆＃34; split_text.py＆＃34;，第80行，in split_pun（word）#passing split_pun中的words函数值以删除标点符号，但这给了我一个错误 NameError：name＆＃39; split_pun＆＃39;未定义

这是代码：

Answer 1

由于os.path.sep是split_pun类中的实例方法，因此您需要从实例中调用它。

UrduCorpusReader应为split_pun(word)
（就像您在其上方使用wordlists.split_pun(word)一样）。

在python中调用函数时出错＆＃34;函数未定义＆＃34;
