Well, I've breezed through Python Coding the Hard Way, until exercise 10. It's a bit of a doozy, in that it introduces the use of "escape sequences" that allow you to format your strings just the way you want. So the most interesting two things I've learned about are these escape sequences and format sequences.
Format sequences include: """, ''' (which does the same thing), %r, %s, %c, %n, etc. I came upon while looking up the functions of these.
while the escape sequences are all listed in the exercise. In particular, I'm not sure of what \a, known as ASCII Bell; and \r, known as carriage return do. My best guess is that carriage return starts the program over again. This could be useful if you needed to take a limit approaching some value, I suppose. You could place the \r in an If-then statement, so that the program would eventually end.
I'm also not sure what the difference is between \f, known as ASCII form-feed; and \v, known as ASCII vertical tab. Both seem to do the same thing.
While looking for an answer, I also found a way to manipulate existing strings by listing the variable representing the string followed by the range of characters I'd like to cut out of it (where the first character is 0, second 1, etc.). This tutorial has been helpful in elucidating many different format sequences.
