Benford Distribution

Hello I am trying to write a code for Benford distribution, but I got this errror:

def leading_digit(n):
    while n >= 10:
        n = n//10
    return n

def Ben(k):
    results = []
    for i in range(k):
        random_number[i] = np.random.randint(10000)
        results.append(leading_digit(random_number[i]))
    return results

Ben(2)

Error message:

---------------------------------------------------------------------------

      5         results.append(leading_digit(random_number[i]))
      6     return results

You should initialize random_number list (random_number = [0] * k) with some value since it reports the variable random_number not defined error.

def leading_digit(n):
    while n >= 10:
        n = n//10
    return n

def Ben(k):
    results = []
    random_number = [0] * k
    for i in range(k):
        random_number[i] = np.random.randint(10000)
        results.append(leading_digit(random_number[i]))
    return results
