What is the output for this code? ```python if None: print('Hi') ``` Options: - Hi - None - Nothing is printed - no output - False
Answer (1)
The code provided is a simple Python conditional statement involving the if keyword. When you place a value after if, Python evaluates this value to determine if it is True or False. Here's a step-by-step explanation of how the code works:
Understanding None in Python : In Python, None is a special constant and is often used to denote the absence of a value or a null value. None is considered False when evaluated in a boolean context.
Evaluating the Condition : In the conditional if None:, Python checks whether None is truthy. Since None is falsy, the condition evaluates to False.
Executing the print Statement : Because the condition is False, the code block inside the if statement (print('Hi')) does not execute.
Output : As a result, nothing is printed to the output and the program produces no output.
Therefore, the correct choice from the given options is:
Nothing is printed - no output
This simple piece of code demonstrates how Python evaluates conditional statements and the nature of the None keyword in a conditional expression.
