Sum of 1 to 10

TIP101 Unit 1 Session 1 (Click for link to problem statements)

U-nderstand

Understand what the interviewer is asking for by using test cases and questions about the problem.

• Should the function print anything?
  • No. Only return the final sum.

P-lan

Plan the solution with appropriate visualizations and pseudocode.

General Idea: Create a function to return the sum of the numbers 1 to 10.

1) Create a variable to store the total sum
2) Loop through the numbers 1 to 10, and add each to the sum variable
3) Return the sum variable

⚠️ Common Mistakes

• We could just write something like 1+2+3+4+5+6+7+8+9+10... why might that be a bad idea?

I-mplement

def sum_ten():
	total = 0
	for i in range(1, 11):
		total += i
	return total

output = sum_ten() # Output: 55
