Question

What will be the output of the following Python code?

def sayHello():
    print("Hello World")

sayHello()
sayHello()

• A. Hello World
• B. Hello World 
  Hello World
• C. Hello World Hello World
• D. None of the above

Hint:

In Python, a function runs only when it is called. If a function containing a print statement is called multiple times, the output will be printed the same number of times.

Answer 1

The Correct Option is B

Step 1: Understand the function definition.
The code first defines a function named \texttt{sayHello()}. Inside this function, there is a print statement that displays the text \[ \texttt{"Hello World"} \] The function does not execute immediately when it is defined. It only runs when the function is called.
Step 2: Observe how many times the function is called.
After defining the function, the program calls the function twice: \[ \texttt{sayHello()} \] \[ \texttt{sayHello()} \] Each time the function is called, the print statement inside the function executes once.
Step 3: Determine the output produced by each call.
The first function call prints \[ Hello\ World \] The second function call prints the same text again on the next line.
Thus the total output becomes \[ Hello\ World \] \[ Hello\ World \] Step 4: Conclusion.
Since the function is executed twice and each execution prints the same message, the output contains two lines of "Hello World". Therefore the correct answer is option (2).
