help needed plz, how to check if a string is almost the same?

[perfringo]

One way of achieving desired result (with Python >=3.6):

- normalize input as Gribouillis suggested
- check whether username in list of users
- print capitalized username with Hello or Try Again

>>> username = input('login: ').split()[0].lower()
>>> users = ['jack', 'jill']
>>> if username in users:
...     print(f'Hello {username.capitalize()}')
... else:
...     print('Try again!')
