python - How to compare two versions of same file (old and new), and detect if there were some changes? -


i new @ both, python , stackoverflow, please have on mind. tried myself , manage it, works if hardcode hash number of previous version 1 in hash1, , compare hash number of version. wolud program every time save hash number of version , every run compare newer version, , if file changed something.

this code

import hashlib  hash1 = '3379b3b9b9c82650831db2aba0cf4e99'  hasher = hashlib.md5()     open('word.txt', 'rb') afile:     buf = afile.read()     hasher.update(buf)     hash2 = hasher.hexdigest()  if hash1 == hash2:     print('same version') else     print('diffrent version')

just save hash file file.txt , when need compare hash read file.txt , compare 2 strings. here example of how read , write files in python. http://www.pythonforbeginners.com/files/reading-and-writing-files-in-python
