本文实例为大家分享了python实现比较文件内容异同的具体代码，供大家参考，具体内容如下
import sys
import difflib
import time
import os
"""

"""
def main():
"""主函数"""
try:
f1 = sys.argv[1]#获取文件名
f2 = sys.argv[2]
except Exception as e:
print("Error: "+ str(e))
print("Usage : python compareFile.py filename1 filename2")
sys.exit()
if f1 == "" or f2 == "":#参数不够
print("Usage : python compareFile.py filename1 filename2")
sys.exit()
tf1 = readFile(f1)
tf2 = readFile(f2)
d = difflib.HtmlDiff()#创建一个实例difflib.HtmlDiff
writeFile(d.make_file(tf1,tf2))#生成一个比较后的报告文件，格式为html
def readFile(filename):
"""读取文件，并处理"""
try:
fileHandle = open(filename, "r")
text = fileHandle.read().splitlines()
fileHandle.close()
return text
except IOError as e:
print("Read file error: "+ str(e))
sys.exit()
def writeFile(file):
"""写入文件"""
diffFile = open('diff_{}_.html'.format(time.strftime("%Y_%m_%d_%H_%M_%S",time.localtime())), "w")
diffFile.write("<meta charset='UTF-8'>")
diffFile.write(file)
print("The file on {}".format(os.path.abspath(str(diffFile.name))))#提示文件生成在什么地方
diffFile.close()
if __name__ == "__main__":
main()
