What are some common Python idioms I should know?
Some common Python idioms include list comprehensions, using 'with' for resource management, and unpacking tuples.
Can you explain list comprehensions with an example?
Sure! A list comprehension allows you to create a new list by applying an expression to each item in an iterable. For example: [x**2 for x in range(10)] creates a list of squares from 0 to 9.
What does 'with' do in Python?
The 'with' statement simplifies exception handling by encapsulating common preparation and cleanup tasks. For example, with open('file.txt') as f: automatically closes the file after the block is executed.
Are there any idioms for handling exceptions?
Yes! A common idiom is to use a try-except block. For example: try: risky_code() except Exception as e: handle_error(e).
