total_cost_of_food = float(input('How much did the food cost? '))
sales_tax = 8.25
tax_plus_total = total_cost_of_food * sales_tax / 100
print("Your tax for this meal was:", tax_plus_total)
x = bool(input("Would you like to add a tip? ")
if x is False
print("Thanks, your total for today is:", tax_plus_total)
else
print("That is", x, "I would like to add a tip")
I keep getting this error for my print statement that is under the if statement, it says it's a syntax error but I don't see anything wrong with the syntax... I have only been coding for about a week though so I am likely missing something.
回答1:
The : is missing, at the end of the if line and the else line
Instead of if x is False, you should use if not x:
Also, you should reduce the indenting of all four lines in your if-else construct, by one level.
回答2:
bool(input("Would you like to add a tip? ") lacks the second closing parenthesis.
Python very often prints a syntax error for the next line or even a subsequent line after that when you have a missing closing parenthesis. It tries to make sense of what you wrote and it takes a while for it to figure out that it really can't.
This also masks the indentation error on the following line, and the lack of a colon at the end of the if and else lines.
