Python file Comparison sample sharing

The code is as follows:

# Compare two strings, if different returns the first one not the same position
# If the same returns 0
def cmpstr (str1, str2):
Col = 0
For C1, C2 in Zip (str1, str2):
if C1 = = C2:
Col + = 1
Continue
else:
Break

#判断是怎样退出循环的, there is another case where the string length is different
If C1! = C2 or len (str1)! = Len (str2):
Return col+1
else:
return 0

file1 = open ("A.txt", ' R ')
File2 = open ("B.txt", ' R ')

FA = File1.readlines ()
FB = File2.readlines ()
File1.close ()
File2.close ()

#用GBK解码 so that you can handle Chinese characters
FA = [Str.decode ("GBK") for STR in FA]
FB = [Str.decode ("GBK") for STR in FB]

Row = 0
Col = 0

#开始比较两个文件的内容
For str1, str2 in Zip (FA, FB):
Col = cmpstr (STR1,STR2)
# col=0 indicates two lines are equal
If col = = 0:
Row + = 1
Continue
Else
Break

#如果有一行不同, or the file length is different
If str1! = str2 or len (FA)! = Len (FB):
#打印出不同的行序和列序, and print out a different sentence after the sentence
#最后两个字符是不同的地方
Print "row:", Row+1, "col:", col
Print "File a is:\n", fa[row-1],fa[row][:col+1], "\ n"
print "File b is:\n", fb[row-1],fb[row][:col+1], "\ n"
else:
Print "All Is same!"

Raw_input ("Press Enter to exit.")
