Выдает ошибку, подскажите как исправить? class Book:
File ".py", line 8, in Book
print(f"{'Название':<30 }{'Автор':<20}{'Год издания':>5}")
ValueError: Unknown format code '\x20' for object of type 'str'

class Book:
def __init__(self, title="Title", author="Author", year="2020") -> object:
self.title = title
self.author = author
self.year = year
book = Book('Title', 'Author', 2020)
book.display()
print(f"{'Название':<30 }{'Автор':<20}{'Год издания':>5}")

def book(self):
if not self.author in Book:
print(f"{self.title:<30}{self.year:>5}")
if not self.year in Book:
print(f"{self.title:<30}{self.author:<20}")
else:
print(f"{self.title:<30}{self.author:<20}{self.year:>5}")
