"To err is human... to really foul things up requires a computer."
Well... except in these cases where it really was just a human causing the problem.
The code at the bottom of page 30 (Chapter 3, "Multiplying Strings") is incorrect - it was supposed to use f-strings and include the variable name spaces
inside the braces as below:
spaces = ' ' * 25
print(f'{spaces} 12 Butts Wynd')
print(f'{spaces} Twinklebottom Heath')
print(f'{spaces} West Snoring')
print()
print()
print('Dear Sir')
print()
