添加一个条件并elif，然后稍微修改if条件：

username = input('''Welcome, {} {} 
what would you like your username to be, it should be something 
memorable and no longer than ten characters long
'''.format(first_name, sur_name))
while True:
        username = input()
        if 0 < len(username) < 10:
                print('''Nice, username''')
                break
        elif not username:
            pass

        else:
            print('''Your username should be a maximum of 10 charecters''')

示例输出：

Welcome, Bob Smith 
what would you like your username to be, it should be something 
memorable and no longer than ten characters long
