In playing around with Pyton 3 dictionaries I've come up with 2 questions
1) How are duplicate keys handled? For example:
Qb_Dict = {"Montana": ["Joe", "Montana", "415-123-4567",
"[email protected]","Candlestick Park"],
"Tarkington": ["Fran", "651-321-7657", "[email protected]",
"Metropolitan Stadidum"],
"Namath": ["Joe", "212-222-7777", "[email protected]", "Shea Stadium"],
"Elway": ["John", "303-9876-333", "[email protected]", "Mile High Stadium"],
"Elway": ["Ed", "303-9876-333", "[email protected]", "Mile High
Stadium"],
"Manning": ["Archie","504-888-1234", "[email protected]",
"Louisiana Superdome"],
"Staubach": ["Roger","214-765-8989", "[email protected]",
"Cowboy Stadium"]}
print(Qb_Dict["Elway"],"\n") # print a dictionary entry
In the above the "wrong" Elway entry, the second one, where the first
name is Ed, is getting printed. I just added that second Elway row to
see how it would handle duplicates and the results are interesting, to
say the least.
Seems like you answered your first question. Dictionaries do not have
duplicate keys. Your 2nd assignment using the key "Elway" replaced the
first.
2) Is there a way to print out the actual value of the key, like
Montana would be 0, Tarkington would be 1, etc?
Actual value? The actual value of Montana" is "Montana". Sounds like you
want the index of the entry as though it were in a list. Dictionaries
are not ordered so you can't get that unless you store it as part of the
value.
