'input' is used to ask the user to input a python expression, which is
then run, and 'input' returns the result of executing that expression. For
example:
(define a function which prints something out)
>>> def func():
... print "You're calling a function"
... return "Function result"
...
(now, call input)
>>> res = input('Type python here: ')
(python outputs the prompt )
Type python here:
(and, if you type the python code to call a function after the prompt)
Type python here: func()
(then python calls the function, which prints out)
You're calling a function
(meanwhile, the result of calling the function gets assigned to 'res')
>>> print res
Function result
'raw_input' just returns whatever text the user typed in. That's what you
want to use here. 'raw_input' returns a string, which you'll need to
convert to a number with the 'int' function, like so:
text = raw_input('Type in a number: ')
number = int(text)

Gaak! it's doing exactly what you told it to do! Bad program! :)
Inside the loop it neither
1) gets further input from the user nor
2) reassigns/sums nu3
Thus, neither of the elements of your condition (nu3 < bigone)
change, so you're stuck in an infinite loop of printing "not
there yet..."
Here's some sample code that works and does about what you
describe. Tweak accordingly. :)
total = 0
target = 3600
values = [
82, 69, 87, 83, 78, 65, 0, 89, 83, 85, 79, 76, 0, 83, 73,
72, 84, 0, 83, 65, 87, 0, 84, 79, 71, 0, 41, 0, 76, 76,
65, 0, 68, 78, 65, 0, 78, 79, 72, 84, 89, 80, 14, 71, 78,
65, 76, 14, 80, 77, 79, 67, 0, 78, 79, 0, 78, 79, 73, 84,
83, 69, 85, 81, 0, 75, 82, 79, 87, 69, 77, 79, 72, 0, 65,
0, 68, 69, 75, 83, 65, 0, 41
]
while total < target:
# still haven't found the value
value = values.pop() # so we get another number
print chr(value+32), #h have a little fun
total += value #accumulate our total
# and do it until we've accumlated more than target
print "Hey...we're over %s" % target

sum = 0
while sum <= 100:
number = int(raw_input("Enter a number\n"))
sum = sum + number
print "Finally there"
As long as the sum is <= 100 the program asks for a number and adds it
to the sum variable. If the variable is >= 100, it exits and outputs the
string.

I can not figure out how to make "Write a program that continually

reaches 100." this work. If someone could show me the correct code so i
can learn from that it would be much appreciated. Thanks

Yes, because you have no input command in the loop and no sum changing
the value of nu3.
But you should get scrolling with "Not there yet, next number please"
not with "Finally there!" according to your code.
I suppose your next question will be what tutorial is the best for a
newbie, so I suggest you start with:

#Add up to 100 program
#What number are you adding up to?
bigone = 100
number = input("Whats the first number?")
number2 = input ("Whats the second number?")
nu3 = number+number2
while nu3 < bigone:
print ("Not there yet, next number please")
print "Finally there!"
thats what i thought maybe it was...but after the first two numbers it
just continually scrolls on the screen with finally there
