[Tutor] TypeError: dict objects are unhashable

[Ben Vinger]

Hello

I want to create a dictionary (from SQL usernames) of
the format:
      accounts = {
      ('psmit', '123456'): 'psmit',
      ('rmatt', 'mypass'): 'rmatt',
      }

So I have:
      accounts = {}
      UserCursor.execute(sqlstr)
      rows = UserCursor.fetchall()
      UserConn.commit()
      for row in rows:
            U = row['User']
            P = row['Password']
            InnerDict = {}
            InnerDict[U] = P
            accounts[InnerDict] = U

But I get:
TypeError: dict objects are unhashable
Unfortunately, I just can't see what I'm doing wrong

Thanks
