Python 比较文件内容是否一致

1、 比较2个文件是否一致，并且渲染出不一致的地方

import difflib
def readfile(filename):
   with open(filename, 'r',encoding='utf-8') as f
    text = f.readlines()
    return text
if __name__ == '__main__':
	d = difflib.HtmlDiff()
	fromlines = readfile('test1')
	tolines= readfile('test2')
	res = d.make_file(fromlines,tolines)
    with open('report.html', 'w+') as f:
        f.write(res)

2、比较文件内容是否一致

import hashlib
import requests
def req(url):
    with open('test.txt','rb) as f :
    	content = f.read()
    	return hashlib.md5(content).hexdigest()
if __name__ == '__main__':
	fromlines = readfile('test1')
	tolines= readfile('test2')
	if tolines == fromlines:
		print('文件内容一致')
	else:
		print('文件内容不一致')
