Return variables on the same line – Python

Question

I’ve got a for loop which iterates through three elements in a list: ["123", "456", "789"].
So, with the first iteration, it will perform a calculation on each digit within the first element, then add the digits back up. This repeats for the other two elements. The outputs are then converted into strings and outputted.

for x in digits:
    if len(x) == 3:
        result1 = int(x[0]) * 8 ** (3 - 1)
        result2 = int(x[1]) * 8 ** (2 - 1)
        result3 = int(x[2]) * 8 ** (1 - 1)

        result = result1 + result2 + result

        decimal = []
        decimal.append(result)

        string = " ".join(str(i) for i in decimal)

        return string

Problem is, when outputting the results of the calculations, it outputs them on separate lines, but I need them to be on the same line.

For example:

123
456
789

I need them to be like this:

123 456 789

I’ve tried putting the results of the calculations into a list, which is then converted to a string and outputted, but no dice – it still returns the values on separate lines instead of one.

EDIT:

I know how to do this using the print function:

print(str(result), end=" ")

But need to use the return function. Is there any way to do this?

Answer 1

you can append each variable on a list using a_list.append('variable') and print it using ' '.join(a_list)
whenever needed.

Answer 2

The problem is that you are creating the list and returning the result inside the for instead of outside. You only make a single calculation and return.

def foo(digits):
    results = []
    for x in digits:
        if len(x) == 3:
            result1 = int(x[0]) * 8 ** (3 - 1)
            result2 = int(x[1]) * 8 ** (2 - 1)
            result3 = int(x[2]) * 8 ** (1 - 1)
            results.append(result1 + result2 + result3)
    return " ".join(str(i) for i in results)
