The assert statement in Python is used during debugging to check for conditions that should always be true. If the condition evaluates to False, an AssertionError is raised.
Basic Syntax
assert condition, optional_message
Example Usage
def divide(a, b):
assert b != 0, 'Divider cannot be zero'
return a / b
Disabling Assertions
Assertions can be disabled globally by running Python with the -O (optimize) flag:
python -O script.py
Conclusion
The assert statement is a useful tool for debugging and ensuring code correctness. Use it to catch errors early in development.
