I am a newcomer, I guess I'm have trouble thinking like a computer yet.
My question is: in this program:
resp = raw_input("What's your name? ")
print "Hi, %s, nice to meet you" % resp
does %s mean 'place the user response here' and secondly what and why
do I put % resp at the end of the print statement?
This is known as a format string and the structure is:
<format_string> % <arguments>
So the format string in your case is
"Hi, %s, nice to meet you"
And every % marker in the string expects a correspomnding argument
The % separates the string from its arguments
and in your case tyou only have %s so you only need one argument which is
resp.
So the format operator(%) substitures the argument resp into the format
string in place of the %s to give the required result.
The format string can contain many % markers each indicating things like
different types, how much space to use, wjether to right pr left justify
the value etc.
You can find out more in vthe Simple sequences topic of my tutor
or by searching for format strings in the docs.
