Python to calculate the sum of the numbers from 1 to 1000, inclusive, except omitting from the summation any number that has a 1 as one of its digits. For example, the sum of numbers from 1 to 10, inclusive without numbers that contain a 1 is: 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 = 44, since we are excluding the numbers 1 and 10 which contain a 1. In this example you would answer with the single integer value 44.  Note that the condition str(1) in str(10) is True, whereas str(1) in str(8) is False
