You are trying to use a dictionary as the key to your dictionary. This
doesn't work - dicts can't be used as dict keys, which is what the error
message is trying to tell you.
Instead of
accounts = {
('psmit', '123456'): 'psmit',
('rmatt', 'mypass'): 'rmatt',
}
your code tries to make
accounts = {
{'psmit': '123456'}: 'psmit',
{'rmatt': 'mypass'}: 'rmatt',
}
try this
accounts[U, P] = U
though I'm not sure why you use a dict instead of a set here, since the
value is contained in the key.
