用python实现两个文件中的数据对比

filename="C:\Users\Administrator\Desktop\data_out\data.txt"
f = open(filename)
c=()
cc=()
while 1:
line = f.readline()
if not line:
break
cc = eval(line)
c = c + cc
s=c
filename="C:\Users\Administrator\Desktop\data.txt"
f = open(filename)
c=()
cc=()
while 1:
line = f.readline()
if not line:
break
cc = eval(line)
c = c + cc
m=0
for i in range(0,len(c[0])):
if c[0][i]!=s[0][i]:
m=m+1
