Traceback (most recent call last):
File "D:\Python24\add_tutor.py", line 18, in -toplevel-
answer, guess = add(num1,num2)
File "D:\Python24\add_tutor.py", line 5, in add
guess = float(raw_input(a," + ",b," = "))
TypeError: [raw_]input expected at most 1 arguments, got 4
The error tells you what to do - give raw input 1 argument:
guess = float(raw_input(a," + ",b," = "))
The commas separate the arguments. You need to create
the prompt string first and then feed it to raw_input.
The string formatting operators may help here.
See the Simple Sequences topic on my tutor for
examples of string formatting.
