Hi,
My goal in this program is to properly explain above lines what they are doing.
I'm unsure what goes on with the last line. I see what it's doing when I run
the program, but I don't know why it's doing it.
# Get some input from the user and work with it.
#
# Print and use a comma to make the input go to the same line as the question.
print "How old are you?",
# Get input and put it into age.
age = raw_input()
# Now, give the prompt and get the input all at once.
# Note that now we have to put a space at the end of the quoted string.
height = raw_input("How tall are you? ")
# Now do it again.
weight = raw_input("How much do you weigh? ")
# Now print out the variables with raw string format specifiers.
# This turns them into single quoted strings properly formatted.
print "So, you're %r old, %r tall and %r heavy." % ( age, height, weight)
# I'm unsure how changing this to %s does what it does.
print "So number 2, you're %s old, %s tall and %s heavy." % ( age, height,
weight)
Thanks.
