I've often thought it was redundant for Python to support 'if'
when it has dictionaries, cf the rationale for having no
'switch'.

valid_name = None
while not valid_name:
    name = input("Enter your name: ")
    valid_name = {
        True: lambda: print("No name longer than 20 letters."),
        False: lambda: True,
    }[len(name) > 20]()

Much better.
