Question

当将以下函数导入Ipython 1.1解释器时，会引发一个SyntaxError，告诉我＆＃34; elif len（org）＆gt; = 1：＆＃34;是无效的语法。我的直接想法是我的间距应该是不正确的，但事实并非如此。

如果我们从第3行的初始for循环遍历此函数，则会在第三组if / elif语句上引发错误。

鉴于这是一个相当单一的功能，最好将其分解为几个较小的功能。这应解决SyntaxError。

您是否同意将此功能分解为较小的功能是解决此错误的最佳方法？你知道为什么在出现间距和语法时出现错误，至少在我看来是正确的吗？

感谢您的时间！

Answer 1

在这里遗漏了一个右括号：

find_full_word.append((n_term, "PERSON"))

Python SyntaxError：“elif len（org）＆gt; = 1的语法无效：”
