Python Loop Accumulator Statement Exercises

Python Loop Accumulator - Ex01

Write a Python program using a while loop to calculate the sum of all numbers from 1 to 100 (i.e., 1 + 2 + 3 + ... + 100).

1. Save your file as "ClassNumber_YourName_Ex01.py"

Use a while loop to iterate through the numbers.

Accumulate the sum of all numbers between 1 and 100, inclusive.

Print the final sum.

Accumulator = \sum_{i=1}^{100} i

The final sum number is 5050

Python Loop Accumulator - Ex02

Write a Python program using a while loop to calculate the total number of apples Alice will have eaten after 30 days, assuming she starts with one apple on the first day and doubles the number each subsequent day (i.e., 1 + 2 + 4 + ... + ?).

1. Save your file as "ClassNumber_YourName_Ex02.py"

Use a while loop to iterate through the 30 days.

Accumulate the total number of apples eaten over the 30 days.

Print the final total of apples eaten.

Total\ Apples = \sum_{i=1}^{30} 2^{i-1}
