Assert Statements in Python

In Python, an assert statement is a way to check if a condition is true. If the condition is true, the program continues to execute. If the condition is false, the program stops and raises an AssertionError exception.

Here is an example of how to use an assert statement in Python:

x = 10

y = 5

assert x > y, "x is not greater than y"

In this example, the condition x > y is true, so the program continues to execute, and no error is raised.

If we change the value of x to be less than y, the condition will be false, and an AssertionError will be raised:

x = 5

y = 10

assert x > y, "x is not greater than y"

Output:

AssertionError: x is not greater than y

Assert statements are useful for testing and debugging code. They can help you identify problems in your code by explicitly checking for conditions that should be true. However, they should not be used for production code, as they can be disabled by the user and do not provide robust error handling.

As previously stated, we can utilise the assert statement in Python in two ways.

If the assert statement’s condition is not met, the application will terminate and throw an AssertionError.

An assert statement can also include a condition and an optional error message. If the condition is not met, assert returns AssertionError with an error message.

• Assertions are boolean expressions or conditions that are always assumed to be true in code.
• The assert statement accepts an expression as well as an optional message.
• The assert statement is used to validate the types, values of arguments, and function output.
• The assert statement is mainly used as a debugging or relevant tool since it stops the programme when an error occurs.
