Concatenation of tuples

1. Normal text:

   • I'm having some problems with coding on python 3.2.1. Actually I'm taking online lectures that 开发者_如何学编程are on python 2.5.

2. Here is the code:

   x = 100
   divisors = ()
   for i in range(1,x):
       if x%i == 0:
           divisors = divisors + (i)
   

3. on running the program, following error appears:

   divisors = divisors + (i)  
   TypeError: can only concatenate tuple (not "int") to tuple
   

(1) is not a tuple, its just a parenthesized expression. To make it a tuple, add a trailing comma, (1,)

Try to use this instead:

divisors.append(i)

Edit:

divisors = []

since you can't append on tuples.
