What is the most common mistake Python beginners make?
—One of the most common mistakes is using manual string formatting instead of f-strings.
Why is it important to use a context manager when working with files?
—Using a context manager ensures that the file is closed properly, even if an exception is thrown.
Why should bare except clauses be avoided?
—Bare except clauses catch all exceptions, including important system exceptions like keyboard interrupts.
What is the purpose of the bitwise XOR operator in Python?
—The bitwise XOR operator is used for bitwise exclusive OR operations, not exponentiation.
Which Python version should beginners use?
—Beginners should use Python 3, as Python 2 is no longer supported.
