方法名拼错了，应该是 writeline 不是 wtriteline

这样试试：


f1 = open("F:/something.txt")
f2 = open("F:/poetry.txt")
   
str1 = []
str2 = []
for each_line in f1:
    str1.append(each_line)
for each_line in f2:
    str2.append(each_line)
   
length = len(str1)
f = open("F:/difference.txt","w")
for i in range(length):
    if str1 != str2:
      string = ("第",i,"行不一样")
      f.writelines(string)
f.close()
   

f = open("F:/difference.txt")
f.read()
