Looping "n" times

I am trying to repeat a for loop a number of times like that

for a in range(0, 100):
    for b in range(0, 100):
        for c in range(0, 100):
            for d in range(0, 100):
                ...
                    print(a, b, c, ...)

but I don't now the number of 'for' loops, so I've written this code:

def inner_for(number, limit=10):
    if number > 0:
        for i in range(limit):
            inner_for(number-1, limit)

The problem is that I don't know how to access the variables of all the 'for' loops
