Write Number in Expanded Form

Definition

Write Number in Expanded Form

You will be given a number and you will need to return it as a string in Expanded Form.

For example:

expanded_form(12) # Should return '10 + 2'
expanded_form(42) # Should return '40 + 2'
expanded_form(70304) # Should return '70000 + 300 + 4'

NOTE: All numbers will be whole numbers greater than 0.

Given Code

def expanded_form(num):
    pass

Solution

def expanded_form(num):
    s = []
    i = len(str(num)) -1
    for n in str(num):
        if n != "0":
            s.append(n + "0" * i)
        i -= 1
    return " + ".join(s)
