Question

programming challenges

1. sum of numbers

write a program that asks the user for a positive integer value. the program should use a loop to get the sum of all the integers from 1 up to the number entered. for example, if the user enters 50, the loop will find the sum of 1, 2, 3, 4, ... 50.
input validation: do not accept a negative starting number.

1. characters for the ascii codes

write a program that uses a loop to display the characters for the ascii codes 0 through 127. display 16 characters on each line.

1. ocean levels

assuming the oceans level is currently rising at about 1.5 millimeters per year, write a program that displays a table showing the number of millimeters that the ocean will have risen each year for the next 25 years.

1. calories burned

running on a particular treadmill you burn 3.6 calories per minute. write a program that uses a loop to display the number of calories burned after 5, 10, 15, 20, 25, and 30 minutes.

Explanation:

Step1: Sum of Numbers in Python

while True:
    num = int(input("Enter a positive integer: "))
    if num > 0:
        sum_num = 0
        for i in range(1, num + 1):
            sum_num += i
        print(f"The sum of integers from 1 to {num} is {sum_num}")
        break
    else:
        print("Please enter a positive number.")

Step2: ASCII Codes in Python

for i in range(128):
    if i % 16 == 0 and i != 0:
        print()
    print(chr(i), end=' ')

Step3: Ocean Levels in Python

print("Year\tMillimeters Risen")
for year in range(1, 26):
    rise = year * 1.5
    print(f"{year}\t{rise}")

Step4: Calories Burned in Python

minutes = [5, 10, 15, 20, 25, 30]
for min in minutes:
    calories = min * 3.6
    print(f"Calories burned after {min} minutes: {calories}")

Answer:

The above Python - code snippets solve each of the programming challenges as described.
