python - 两个字符串（句子）之间的区别

Question

我试图计算两个句子之间的差异，如下所示：

import difflib

text1_lines = "I understand how customers do their choice. Difference"
text2_lines = "I understand how customers do their choice."
diff = difflib.ndiff(text1_lines, text2_lines)

我想有所作为

但我不明白。我究竟做错了什么 ？谢谢你让我知道。

来自文档：

import difflib
import sys

text1_lines = "I understand how customers do their choice. Difference"
text2_lines = "I understand how customers do their choice."
diff = difflib.context_diff(text1_lines, text2_lines)
for line in diff:
    sys.stdout.write(line)

输出：

*** 
--- 
***************
*** 41,54 ****
c  e  .-  - D- i- f- f- e- r- e- n- c- e--- 41,43 ----
