comparison of two string differences

This example uses the Difflib module to achieve the difference between the two strings and then output in a versioning style.

>>>ImportDifflib>>> >>> text1="Difflib Document v7.4" #定义字符串1 >>> text2="Difflib Document v7.5" #定义字符串2 >>> >>> text1_lines=text1.splitlines () #进行分割 for comparison >>> text2_lines=Text2.splitlines ()>>> >>> diff=Difflib. Differ () #创建Differ () object >>> >>> differ=Diff.compare (text1_lines,text2_lines) #采用compare方法对比字符串>>> >>>Print('\ n'. Join (list (differ)))-Difflib Document v7.4? ^+Difflib Document v7.5? ^>>>

//Comment: Description of the meaning of the symbol
//-#包含在第一个序列行中, but not included in the second sequence line
//+ #包含在第二个序列行中, but not included in the first sequence line
//Empty #两个序列行一致
//? #两个序列行存在增量差异
//^ #两个序列行存在差异字符

generate aesthetically pleasing contrast HTML-formatted documents

An aesthetically pleasing HTML document can be generated using the Make_file () method of the Htmldiff () class.

Import difflib>>> >>> text1_lines=text1.splitlines ()>>> text2_lines=  Text2.splitlines ()>>> >>> >>> text1_lines=text1.splitlines ()>>> text2_lines=text2.splitlines ()>>> >>> diff=difflib. Htmldiff ()print(Diff.make_file (text1_lines,text2_lines))
