如何从python中的字符串中提取单词？

Question

我有

形式的字符串

 sent="Software Development = 1831".

我想只从字符串中提取单词，即＆＃34;软件开发＆＃34;。我如何在Python中提取它。

Answer 1

您可以尝试split：

>>> sent="Software Development = 1831"
>>> sent.split("=")[0]
'Software Development '

Answer 2

>>> str="Software Development = 1831"

>>> str.split()
['Software', 'Development', '=', '1831']

or 

>>> str.split("=")
['Software Development ', ' 1831']

Answer 3

最初，您在＆＃39; =＆＃39;之间有空格，因此您的代码应如下所示

  

sent =＆＃34;软件开发= 1831＆＃34;

     

answer = sent.split（＆＃34; =＆＃34;）[0] #space = =之前和之后
