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

[john pierce]

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.

John
