Python Coding Challange - Question with Answer (01200725)

 

Step-by-Step Explanation

1. Initialize a variable:

   
   total = 0

   • A variable total is created and set to 0. It will be used to accumulate the sum.

2. For loop:

   
   for i in range(1, 5):
       total += i

   • range(1, 5) generates the numbers: 1, 2, 3, 4 (remember, the end is exclusive).

   • The loop adds each of these values to total.

   Here's what happens on each iteration:

   • i = 1: total = 0 + 1 = 1

   • i = 2: total = 1 + 2 = 3

   • i = 3: total = 3 + 3 = 6

   • i = 4: total = 6 + 4 = 10

3. Print the result:

   
   print(total)

   • It prints the final value of total, which is:

---

✅ Output:

10

---

Key Concept:

• range(start, end) includes the start but excludes the end.

• += is a shorthand for total = total + i.
