How to Use if/else Expressions in Python
Now that conditional operators are clear, they can be used to make the code branch based on specific conditions. In Python, this is achieved using the following structure:
if condition:
# Execute this if the `condition` is `True`
else:
# Execute this if the `condition` is `False`
The condition can be a conditional statement or a boolean value. The commands under if and else are executed based on whether the condition is met. These commands can include operations like printing, variable assignments, arithmetic, or string manipulations.
123456789# Initialize a boolean variable is_active = True if is_active: # Execute this block if `is_active` is `True` print("The system is active") else: # Execute this block if `is_active` is `False` print("The system is inactive")
Each block of code under if and else must have consistent indentation. Using inconsistent indentation will result in an error, causing the code to fail.
