The md5.update of Python.

Look at the code:

>>> import hashlib>>> md5=hashlib.md5 () >>> md5.update (' 123 '. Encode (' Utf-8 ')) >> > Print (Md5.hexdigest ()) 202cb962ac59075b964b07152d234b70>>> md5.update (' 123 '. Encode (' Utf-8 ')) > >> print (Md5.hexdigest ()) 4297F44B13955235245B2497399D7A93//have not found the same result as above for the string "123" MD5 encryption

After testing that Md5.update would stitch each string together, we looked at the result of "123123" as follows:

>>> md5=hashlib.md5 ()//redefine md5>>> md5.update (' 123123 '. Encode (' Utf-8 ')) >>> print (md5.he Xdigest ()) 4297F44B13955235245B2497399D7A93//Discovery 123123 and the results above verify that the md5.update is the stitching effect.

To prevent this interference we have to re-instantiate each time:

Redefine every time you use Update: MD5=HASHLIB.MD5 ()

eg

Import HASHLIBF = open (' Top10.md5.txt ', ' w ') p = open (' Top10.txt ', ' r ') for I in P:MD5 = Hashlib.md5 () I=i.strip ()/ /filter white space character md5.update (I.encode (' Utf-8 ')) c=md5.hexdigest () c=c+ ' \ n ' f.write (c)
