Question

What statement do you use in Python to write a dual alternative decision structure?

Short answer

Answer: The "if-else" statement is used in Python to create a dual alternative decision structure. This allows the code to follow one path when a condition is met (True) and another path when the condition is not met (False). The syntax for the basic if-else statement is: ``` if condition: # Execute this block of code when the condition is True else: # Execute this block of code when the condition is False ```
