But i keep getting this error :

    print(dic[0])
KeyError: 0

Answer 1

Try:

print(dic['days']) 

You refer to values by keys. It returns a list of elements. Then, if you want a specific element, just use:

print(dic['days'][0])

...as you would do with a normal list.

Answer 2

Dictionaries in python are accessed via key not index as position was not guaranteed until 3.7.

dic = {"days":["mon","tue","wed"]}
print(dic["days"])

Answer 3

Thanks everyone i Found the answer

dic = {"days":["mon","tue","wed"], "months":["jan","feb","mar"]}
print(list(dic.values())[0])

the output will be:

['mon', 'tue', 'wed']

Thank you
