It runs, the difference between input and raw_input in matter of use is =
just that when you use just plain input you'll have to add ' or " to =
your reply if it's made up of chars.
>>> name =3D input("Please enter your first name:")
Please enter your first name:Ulf
Traceback (innermost last):
File "<pyshell#0>", line 1, in ?
name =3D input("Please enter your first name:")
File "<string>", line 0, in ?
NameError: Ulf
>>> name =3D input("Please enter your first name:")
Please enter your first name:'Ulf'
>>> name
'Ulf'
>>> num =3D input("Please enter a number:")
Please enter a number:5
>>> num
5
>>> name =3D raw_input("Please enter your first name:")
Please enter your first name:Ulf
>>> name
'Ulf'
Conclusion: Unless you're dealing with numbers-only, use raw_input. =
Still it's a lot easier than starting with C++, which was one of my =
first languages. ;)
