python实现两个字符串比对差异点

一：代码实现

import difflib, re# 比较两个文本差异点
def compare_text_index(text1, text2):# 创建SequenceMatcher对象matcher = difflib.SequenceMatcher(a=text1, b=text2)# 获取差异报告diff_report = matcher.get_opcodes()# 检查差异报告中是否存在关键词错误for tag, i1, i2, j1, j2 in diff_report:if tag == 'replace':print("{0} with {1}".format(text1[i1:i2], text2[j1:j2]))elif tag == 'delete':# 检查删除操作中是否包含关键词print("{0} with {1}".format(text1[i1:i2], text2[j1:j2]))elif tag == 'insert':# 检查插入操作中是否包含关键词print("{0} with {1}".format(text1[i1:i2], text2[j1:j2]))return Nonetext1 = "四位导师通过盲选选择自己心仪的学员组成战队."
text2 = "四位到时候通过盲选选择自己sds的学员组成站队."
compare_text_index(text1,text2)

运行结果：

导师 with 到时候
心仪 with sds
战 with 站
