Python interview questions covering recursion, data types, exception handling, memory management, and more.

Recursion is a function that calls itself. Example: factorial function.
Python data types include integers, floats, strings, lists, tuples, and dictionaries.
Negative indexing allows you to access elements from the end of a list or string. Example: my_list[-1] returns the last element.
Exceptions are handled using try-except blocks. Example: try: some_code except SomeException as e: handle_exception(e)
The with statement is used for resource management. Example: with open('file.txt', 'r') as f: do_something(f)
*args and **kwargs are used to pass a variable number of arguments to a function. Example: def my_func(*args, **kwargs):
Generators are functions that return an iterator. Example: def my_gen(): yield 1
range and xrange are used to generate a sequence of numbers. xrange is more memory efficient for large sequences.
Python uses automatic memory management through garbage collection.
__init__.py is a special file used to mark a directory as a Python package.
