I noticed that too, Liam.
b = input("Weather is really bad, still go out to jog? [y/n] ") # Would
it kill you to have whitespace in a prompt?
should really be
b = raw_input("Weather is really bad, still go out to jog? [y/n] ")
to get the effect he wants.
input() doesn't only take integers, it takes valid python objects. Integers
are objects, but so are lists, dictionaries, tuples,
actually it takes everything, BUT!!! it trys to return a valid python object
for input.
So it will take a string--don't quote me on this--if you explicitly put the
string in quotes.
If you don't put the string in quotes, it instead searches the namespaces
for that object.
So say the user typed in bad_weather when the interpreter gave that prompt.
Then, b == "y" evaluates true because bad_weather == "y". Did I explain it
right? Or am I trying to explain something you already know? I know I get
frustrated when people try to explain concepts that I already know...
HTH,
Jacob Schmidt
