What are some common Python idioms with examples?

Python idioms are common patterns or best practices in Python programming. For example, using list comprehensions is a popular idiom for creating lists. Here's an example:

squares = [x**2 for x in range(10)]

This creates a list of squares from 0 to 9.

Can you give me more examples of Python idioms?

Sure! Another common idiom is using the with statement for resource management. For example:

with open('file.txt', 'r') as file:
    data = file.read()

This ensures that the file is properly closed after its suite finishes.

What about idioms for handling exceptions?

A common idiom for handling exceptions is using try and except. For example:

try:
    result = 10 / 0
except ZeroDivisionError:
    print('You cannot divide by zero!')

This catches the exception and allows you to handle it gracefully.

Are there idioms for working with dictionaries?

Yes! A common idiom is using the get method to avoid KeyErrors. For example:

my_dict = {'a': 1, 'b': 2}
value = my_dict.get('c', 0)  # returns 0 if 'c' is not found

This way, you can provide a default value.
