Hi everyone - I am doing the first problem set (#0) and I have almost figured it out and got it working but when I run the module it asks the two questions twice before it outputs your name and d.o.b together. Can anyone help?

actually never mind - i figured it out! But it would be great if someone could have a look at my final source code to see if it is in fact correct or if there is another way you could do it. This is what I ended up with: dob = raw_input('What is your date of birth? ') name = raw_input('What is your last name? ') print(name + dob)
this code is absolutely right as you are taking name and dob as strings and then adding them up
is there a space between name and dob? is that what you intended? another way might be; print name, dob

An easier to understand version of the space could be a literal concatenation: print name + " " + dob
I think your code is right for python 3, but not for version 27. Does it matter which one we use for this course?
His code is good for v2.x. V3 uses input() instead of raw_input().
Thanks for your input guys! I didn't intend for there to be aspace but I wasn't sure if there needed to be a space either side of the '+' sign but I wil keep your comments in mind for when I do want a space :) Thanks everyone you have been super helpful.
The space on the side of the plus sign is an optional matter of syntax. When you're concatenating strings, you get exactly what you specify: print "Hello" + "World" # is probably wrong print "Hello " + "World" # is probably right
