Python Coding Challange - Question with Answer (01230725)

 

Step-by-Step Explanation

1. Define a global variable:

   count = 0

   • A variable count is initialized in the global scope with value 0.

2. Define a function counter:

   def counter():
       global count 
       count += 1

   • The global keyword tells Python:

     "Use the count variable from the global scope, not a new local one."

3. First function call:

   counter()

   • count += 1 → count = 0 + 1 → count = 1

4. Second function call:

   
   counter()

   • count += 1 → count = 1 + 1 → count = 2

5. Print the result:

   
   print(count)

   • This prints:

     2

✅ Output:

2

Key Concept:

• global allows a function to modify a variable defined outside the function.

• Without global, Python would assume count is local, and you'd get an UnboundLocalError.
