How to write Python program with output like this: Limit: 18 The consecutive sum: 1 + 2 + 3 + 4 + 5 + 6 = 21

Question

My code looks like this at the moment:

    limit = int(input("Limit:"))
    number = 1
    sum = 1

    while sum < limit:
        number = number + 1
        sum = sum + number

    print(f"The consecutive sum:{sum}")

Answer 1

Add the numbers you're using in a separate list. Then use str.join() to join these numbers with a ' + '.

limit = int(input("Limit:"))
number = 1
total = number
numbers = [str(number)]

while total < limit:
    number = number + 1
    total = total + number
    numbers.append(str(number)) # Need to convert to string here because str.join() wants a list of strings

print(f"The consecutive sum: {' + '.join(numbers)} = {total}")

Which prints the required output:

The consecutive sum: 1 + 2 + 3 + 4 + 5 + 6 = 21
