Exercise 2

• Fix the Python code so even if the user does not supply the "name" field it still won't crash.

• Instead make it return a JSON structure with status "400 Bad Request"

• Use curl -I or curl -D err.txt to check the headers as well.

• Create another function that will accept 2 numbers (parameters a and b) and add them together returning a JSON that looks like this:

{
   'a' : 23,
   'b' : 19,
   'op' : '+'
   'result' : 42
}
