there is some error about the sample function, in ex 4,
but the sample function is correct.
(here is the feedback from grader:Code Cell UNQ_C2: Function ‘sample’ is correct.)
and the 3 arguments of sample function is correctly defined in the ex 4 code
88 # Sample indices and print them
---> 89 sampled_indices = sample(parameters, char_to_ix, seed)
90 last_dino_name = get_sample(sampled_indices, ix_to_char)
91 print(last_dino_name.replace('\n', ''))
**TypeError: sample() takes from 1 to 2 positional arguments but 3 were given**
