比較並找出兩個文本內容的不同

import difflib

text1="""1. Beautiful is better than ugly.
2. Explicit is better than implicit.
3. Simple is better than complex.
4. Complex is better than complicated.
""".splitlines(keepends=True)

text2="""1. Beautiful is better than ugly.
3.   Simple is better than complex.
4. Complicated is better than complex.
5. Flat is better than nested.
""".splitlines(keepends=True)

#第一種方式：
d = difflib.Differ()
result = list(d.compare(text1,text2))
result = ‘‘.join(result)
print(result)
"""
運行結果以文本行方式顯示，不容易理解
"""

#第二種方式：
d = difflib.HtmlDiff()
with open(‘diffirent.html‘,‘w‘) as f:
    f.write(d.make_file(text1,text2))
"""
生成一個html文件，用瀏覽器打開，會顯示兩個文本內容的不同之處
"""
 

第一種方式：

第二種方式：

直接比較兩個文件：

import difflib

file1 = ‘/etc/passwd‘
file2 = ‘/tmp/passwd‘

with open(file1) as f1,open(file2) as f2:
    text1 = f1.readlines()
    text2 = f2.readlines()

d = difflib.HtmlDiff()
with open(‘passwd.html‘,‘w‘) as f:
    f.write(d.make_file(text1,text2))
