Yes, stdout.write has no formatting if you need spaces or newlines you
have to explicitly provide them. That's why mosty folks use print
combined with a format string to get formatted output.

You're welcome but the web pages are more up top date than
the pdf file. I only generate the pdf after major updates but the
html files get updates fairly regularly. The zip files get updates
somewhere in between

I don;t know what "str input" refers to but raw_input is the standard
method in Python v2 of reading characters from stdin.  Its called raw
because it reads the raw characters, it does not try to interpret them.
Thus if you know its a number you use int() to convert the string to
an integer value

In Python v3 raw_input has been renamed to input()

See the Talking to the User topic in my tutorial for more detail on the
differences.
