Re: Help with my 8-year old son's first program. I'm stuck topic

First, forget about the def a() statement. def is for defining a function and this is not a function. Second, research the difference between == (logical test) and = (assignment operator). Third, take a look at the length of "op" just after the readline(). You can add a line that says

print(len(op))

right after the readline to see what's goingon. There's a new line character in there. Try using

op = op.strip()

before you do all the if statements. That will remove the trailing newline, and change the first test back to op == "d".

Hope this helps.
