Learn how to compare two strings in Python and understand their advantages and drawbacks for effective string handling.
Hash functions are generally applied over passwords and store then encrypted strings in database. In this way, user password is never stored in any plain text form in the system and makes security robust. Similarly, when want to transfer a secure file to another host – we also pass the fi...
However, in the .__deepcopy__() method, you create a new, independent copy of .history by explicitly calling copy.deepcopy() on the original one with the memo argument. Python would’ve done the same by default. Finally, you add the newly created window tab to the global registry and...

has not been modified or tampered with since its creation. Additionally, because hash-based technology relies on irreversible algorithms which scramble data in an unpredictable manner, hashes are also used as a way to 'mask' credentials when storing them in a database (such as salted-hashing)....
