Submission of Assignment 02

Don't be so hard on yourself Kevin. You're actually doing really well. I make this homework challenging for a reason.

Using the modulus operator with a string (`%`) is the old-style formatting string. The author briefly discusses both but we're going to use the new style for this course.

The documentation for the official mini-language is here:

https://docs.python.org/2.7/library/string.html#format-specification-mini-language

It's pretty dense so let me help you out here by unpacking it a bit:

    {X:Y}

`X`, in this case, is the variable you intend to replace. That might be a numeric index (eg, 0,1,2) or a named variable. You can see examples of both in the course text and in the link above.

`Y`, is the formatting string. (your 06d part) which roughly means 0-padded to 6 characters and must be a digit (integer).
