[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
