Question

[Exceptions, Function calling another function] Write a function ticker() that first runs (calls) read_ticker() and then stores the returned dictionary. It then runs an interactive loop with the user in which the user is prompted for a company name. If the company name (key) is in the dictionary, then its ticker form and the IPO year is printed. Otherwise a warning is printed that the company name is not in the list. If the user just hits return without entering a name, the loop stops.
this is the function that needs to be called:
def read_ticker():
d = {'1347 Capital Corp.': ('TFSCW', '2014'), '1347 Property Insurance Holdings, Inc.': ('PIH', '2014'), '1-800 FLOWERS.COM, Inc.': ('FLWS', '1999')}
return d

Answer 1

def read_ticker():

   d = {'1347 Capital Corp.': ('TFSCW', '2014'), '1347 Property Insurance Holdings, Inc.': ('PIH', '2014'),

        '1-800 FLOWERS.COM, Inc.': ('FLWS', '1999')}

   return d

def ticker():

   di = read_ticker()

   while True:

       try:

           name = input("Enter the name of a company: ")

           if name == "":

               return

           print(di[name])

       except KeyError:

           print("Name not found! Please enter a valid name!")

ticker()

I hope this helps!
