因工作需求，需要對(duì)比連個(gè)文件異同，并輸出html格式來(lái)對(duì)比。

#!/usr/bin/python

# -*- coding: utf-8 -*-

import sys

import difflib

def read_file(filename):

try:

with open(filename, 'r') as f:

return f.readlines()

except IOError:

print("ERROR: 沒(méi)有找到文件:%s或讀取文件失敗！" % filename)

sys.exit(1)

def compare_file(file1, file2, out_file):

file1_content = read_file(file1)

file2_content = read_file(file2)

d = difflib.HtmlDiff()

result = d.make_file(file1_content, file2_content)

old_str='charset=ISO-8859-1'

new_str='charset=UTF-8'

with open(out_file, 'w') as f:

f.writelines(result.replace(old_str,new_str))

if __name__ == '__main__':

compare_file(r'd:\1\a.log', r'd:\2\a.log', r'd:\result.html')

輸出為一個(gè)result.html文件，打開后已于瀏覽。

還有一種需要，需要手動(dòng)要檢測(cè)的腳本

difflib模塊文件內(nèi)容差異對(duì)比

源碼a.py如下：(對(duì)比兩個(gè)配置文件差異)

#!/usr/bin/env python

# -*- coding: utf-8 -*-

import difflib

import sys

try:

textfile1 = sys.argv[1]

textfile2 = sys.argv[2]

except Exception,e:

print "Error:" +str(e)

print "Usage: python sample3.py filename1 filename2"

sys.exit()

def readfile(filename):

try:

filehandle = open(filename,'rb')

text = filehandle.read().splitlines()

filehandle.close()

return text

except IOError as error:

print ('Read file Error:' +str(error))

sys.exit()

text1_lines = readfile(textfile1)

text2_lines = readfile(textfile2)

d = difflib.HtmlDiff()

print d.make_file(text1_lines,text2_lines)

用法：

python a.py nginx.conf.v1 nginx.conf.v2 > sample3_diff.html

總結(jié)

以上是生活随笔為你收集整理的pythonhtml内容比较_Python使用difflib模块比较两个文件内容异同，同时输出html易浏览...的全部?jī)?nèi)容，希望文章能夠幫你解決所遇到的問(wèn)題。

如果覺(jué)得生活随笔網(wǎng)站內(nèi)容還不錯(cuò)，歡迎將生活随笔推薦給好友。
