Nested loops with depth parameter in python

How do I make a number of nested loops where depth is a parameter. I am thinking of a function which takes depth as a parameter

def make_nested_loops(depth):
    ...

And, the result for depth=3 is the following

for i1 in range(10):
    for i2 in range(i1 + 1, 10):
        for i3 in range(i2 + 1, 10):
            # do stuff

So far I've been able to do this using strings building and exec command. But I think there is better and more efficient way to do it.
