Can we use two or more same keys in a dictionary?

Question

just like joe:24,joe:12,jet:28

Answer 1

yeah

Answer 2

Yes you can, but only the last one entered will remain as part of the dictionary,

Take into account the following code:

myDict = {"joe": 23, "joe":55, "ben":34} # first element is is changed to 55 by second
# our dictionary is actually {"joe": 55, "ben":34}

print(myDict["joe"]) # outputs 55 not 23
print(myDict["joe"]) # again outputs 55 not 23
print(myDict["ben"]) # outputs 34
print(len(myDict)) # when checking the length of the dict you get 2 instead of 3

Answer 3

Yes use a list...

myDict = {"Bob":[1,2,3]}

you can store multiple values. You can call them by using...

myDict["Bob"][0] # output is 1

Answer 4

can list(d.keys()) out put the joe,joe,ben or joe,ben ?
