How do i append into dict?

And if you need the index of each element in an iterable (e.g. list) you should do it this way:

patients = ['Bob', 'Alice', 'Guido', 'Janet', 'Pamela'] 
for index, patient in enumerate(patients):
    print(f'{index}: {patient}')

... and if you want indices starting other than from zero use start= in enumerate
