What are some examples of assertions in Python?

Assertions in Python are used to test if a condition is true. If the condition is false, an AssertionError is raised. For example:

assert x > 0, "x must be positive"

This checks if x is greater than 0.

Can you give me another example?

Sure! Here's another example:

assert len(my_list) != 0, "List should not be empty"

This ensures that my_list is not empty.

What happens if the assertion fails?

If the assertion fails, Python raises an AssertionError and stops the execution of the program unless handled with a try-except block.

When should I use assertions?

Use assertions to catch programming errors during development. They help ensure that your code behaves as expected.
