When something goes wrong, Python stops and prints a traceback. The last line is the important one: the kind of error and a message. NameError: name 'totl' is not defined means you used a name that was never assigned, usually a typo. TypeError: can only concatenate str (not "int") to str means you tried to glue text and a number with +; convert the number with str() or use an f-string. SyntaxError means Python could not even read the line, often a missing quote or parenthesis; the caret points near the problem.
The line number in the traceback is where to look. Fix one error, run again, and the next one appears; that is normal.
Your task
The starter has three bugs. Fix them so the program prints Total: 42 on the first line and Done on the second, without changing what it is trying to do.
Hint 1
Run it and read the last line of the error. Fix that one thing, then run again.
Hint 2
A number cannot be added to text with +. Use print(f"Total: {total}") or str(total).
Show the solution
price = 40
tip = 2
total = price + tip
print(f"Total: {total}")
print("Done")
