After the object id of str1 is changed, the result of str1 and str2 will be false. You may ask, why would I learn to compress files in Python where there are already provided tools out there? After that, I made an optional parameter 'member' in case we want to extract specific files (not all archives), if 'members' isn't specified, we gonna get all files in the archive using the getmembers() method which returns all the members of the archive as a Python list.
os.path.getmtime(path) Here, path represents the path of file and it returns the last modification time of file in terms of number of seconds since the epoch. Based on the outcome of that comparison we get a single True or False value as the result (Sweigart, 2015). Python - Write String to Text File. We would be using Cryptographic Hashes for this purpose.
