Using function argument in lists comprehension.

[blackknite]

def nb_dig(n,d):
    r = [n**2 for n in range(1,n)]
    digz = [d for d in r]
    print(r,digz)
nb_dig(10,1)

Output:
>>>[1, 4, 9, 16, 25, 36, 49, 64, 81] [1, 4, 9, 16, 25, 36, 49, 64, 81]

So, I want 'd' to be a string value, telling me how many times certain number occurs in the results, but instead of it I get some bs. Why the damn 'd' in digz is not imported from the function parameters?
