How to fix the function issue while allowing it to be dynamic?

Let's say i'm calling a function given the following arguments 

Function(char1, char2, char3, char4, Number)

where the first 4 terms represent chars and the last is an int, i might add more chars so the function can't be static . The main function will start like 

def Function(*args):
  table_line = ""
  for x in range(Number/2):

but by giving the Function args it no longer knows that it should use the supplied argument number in that third line.

If you're using python3.x (which you're now not, as you mentioned in the comments), you could unpack your args using * iterable unpacking, before using them:

def function(*args):
    *chars, number = args
    ...

It works like this:

In [8]: *a, b = (1, 2, 3, 4)

In [9]: a
Out[9]: [1, 2, 3]

In [10]: b
Out[10]: 4

Every element in args except the last is sent to chars, which now becomes a list. You may now use the number variable as a separate variable.

Pass number as the first argument:

def func(number, *char):
    ...
