Sample questions

1. What is a function in Python?

   1. A block of code that performs a specific task
   2. A type of variable
   3. A data structure
   4. A loop
   Show answer

   Answer: A. A block of code that performs a specific task

   A function is a reusable block of code designed to perform a specific task.

2. What is a function parameter?

   1. A variable declared inside a function
   2. The value returned by a function
   3. A variable in the function definition that receives an argument
   4. A type of loop
   Show answer

   Answer: C. A variable in the function definition that receives an argument

   Parameters act as placeholders for the arguments passed during function call.

3. What happens if a recursive function lacks a base case?

   1. The function executes correctly
   2. The program crashes
   3. The function returns an error
   4. The program enters an infinite loop
   Show answer

   Answer: D. The program enters an infinite loop

   Without a base case, the function will call itself repeatedly without stopping.

4. How can you access a global variable from inside a function?

   1. You cannot access global variables from inside a function
   2. By declaring the variable as 'global' inside the function
   3. By passing the variable as an argument to the function
   4. By using the 'global' keyword before accessing the variable
   Show answer

   Answer: D. By using the 'global' keyword before accessing the variable

   Using the 'global' keyword explicitly indicates that you want to modify the global variable.

5. What is the difference between *args and **kwargs?

   1. *args accepts keyword arguments, **kwargs accepts positional arguments
   2. *args accepts a variable number of positional arguments, **kwargs accepts a variable number of keyword arguments
   3. Both are the same
   4. *args is used for recursion, **kwargs for iteration
   Show answer

   Answer: B. *args accepts a variable number of positional arguments, **kwargs accepts a variable number of keyword arguments

   They are used to handle flexible function signatures.
