Question

i am new to python and i am having trouble on python dictionaries this is my code:

the output am expecting is

"mon","tue","wed"

But i keep getting this error :

    print(dic[0])
KeyError: 0

please help me... Thank You!

`dic['days']` instead of `dic[0]`, if you want to obtain according to the insertion order, consider using `list(dic.values())[0]`. — Mechanic Pig, Jun 18 '22 at 16:20
Or this way - `print(dic['days'][0])` It's because your `values` in the dict is a `list`. — Daniel Hao, Jun 18 '22 at 16:21

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.

As far as I know, you cannot access values in dictionaries by indices, only by keys. That's just how it works. – jarsonX Jun 18 '22 at 16:41

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"])

what is there is another key and i want only the first one – Prison Mike Jun 18 '22 at 16:32
What do you mean ? dicts can only have one of each key, you cannot have `dic = {"days": ["mon","tue","wed"], "days": ["thu", "fri"]}` – ljmc Jun 18 '22 at 16:39

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

Note, this is will only work with python 3.7 and above ([ref](https://mail.python.org/pipermail/python-dev/2017-December/151283.html)). – ljmc Jun 18 '22 at 16:50
