Question

What will be the output of the following Python code? Explain how the variables are updated during the execution (Note: no credits if only give the result).

Answer 1

The output of the Python code will be '9 10 11 5'. During the execution, the variable 'num' is updated by incrementing it by 1 inside a function.

Step-by-step explanation:

The output of the given Python code will be '9 10 11 5'.

During the execution of this code:

• The variable 'num' is initially assigned the value 9.
• The variable 'num' is passed to the function 'update_num' and the value of 'num' is incremented by 1 inside the function, resulting in 10.
• The variable 'num' is accessed outside the function and its value is printed.
• The variable 'num' is assigned the value 11.
• The variable 'num' is passed to the function 'update_num' again and the value of 'num' is incremented by 1 inside the function, resulting in 12.
• The variable 'num' is accessed outside the function and its value is printed.
• The variable 'num' is assigned the value 5.
• The variable 'num' is passed to the function 'update_num' once more, but this time the value of 'num' is not modified inside the function as the parameter has the same name as the local variable. Therefore, the value of 'num' remains 5.
• The variable 'num' is accessed outside the function and its value is printed one final time.
