Python Question

I am trying to figure out a way to modify the order of a list of tuples within a function without returning the list.

For example:

`L = [(2,4),(8,5),(1,3),(9,4)]`

def sort_ratios(L):

L = sorted(L, key=lambda x: float(x[0])/float(x[1]))

return L

Thus, calling sort_ratios() outputs:

`>>>sort_ratios(L)`

[(1,3),(2,4),(8,5),(9,4)]

But

`L`

`[(2,4),(8,5),(1,3),(9,4)]`

Instead, I would like to simply modify the value of L without returning anything so that

`sort_ratios()`

`>>>sort_ratios(L)`

>>>L

[(1,3),(2,4),(8,5),(9,4)]

It seems trivial, but I just can't seem to get the function to operate this way.
