sales = [1000, 2000, 1500, 3000]

total = 0

for amount in sales:
    total += amount

print(total)

Output: 7500

🔹 11. Common Mistakes 

❌ Forgetting to update the loop variable

count = 1
while count <= 5:
    print(count)

This creates an infinite loop because count never changes.

Correct:

count = 1
while count <= 5:
    print(count)
    count += 1

🎯 Practice Questions 

1. Print numbers from 1 to 10 using a "for" loop

2. Print even numbers from 2 to 20

3. Find the sum of numbers from 1 to 100

4. Print all elements of a list using a loop

5. Create a multiplication table of any number using a "for" loop

🎯 Key Takeaways

✅ Use a "for" loop when the number of iterations is known

✅ Use a "while" loop when the number of iterations depends on a condition

✅ range() generates sequences of numbers

✅ break exits the loop immediately

✅ continue skips the current iteration

✅ pass acts as a placeholder

Loops are one of the most important concepts in Python. You'll use them extensively for data processing, feature engineering, machine learning, automation, and solving coding interview questions.
