I have some code that I want to ask the user for a number between 1-100 and if they put a number between these it will print (Size: (input)) and break the loop, if however, they put in a number outside 1-100 it will print (Size: (input)), and proceed to re-ask them for a number, I have run into some problems though.

c=100
while c<100:
    c=input("Size: ")
    if c == 1 or 2 or 3:
        print ("Size: "+c)
        break
    else:
        print ("Size: "+c)
        print ("Invalid input. Try again.")

Any help would be much appreciated!

"I have run into some problems" - what problems? – sashkello Apr 18 at 2:58

When asking a question tell us HOW it doesn't work. You get error? It gives output you don't expect? What exactly is wrong? – sashkello Apr 18 at 3:02

This should do it.

c=input("Size: ")
while int(c)>100 or int(c)<1: 
    #Will repeat until the number is between 1 and 100, inclusively.
    #It will skip the loop if the value is between 1 and 100.

    print ("Size: "+c)
    print ("Invalid input. Try again.")
    c=input("Size: ")

#once the loop is completed, the code following the loop will run
print ("Size: "+c)

You never even enter your loop.

c=100
while c<100:

c is initiated at 100 and while checks if it is less than 100.
