TypeError: 'int' object is not subscriptable

Question

I have the following code

d1={'key1':[1,2,3],'key2':[4,5,6]}
d1['key2'][0][2]

which produces this error:

TypeError: 'int' object is not subscriptable

I want the output to be 4,6

`d1['key2'][0]` return `4`, and you cannot subscript `int`, ergo the mentioned error — han solo, Apr 13 '19 at 10:24
Hi han Solo. Thanks for answering. Can you please explain what is meant by you cant subscript int. — VIgnesh Nagaraj, Apr 13 '19 at 10:40

You are using subscription operation on a list item which is an integer (4 in this case), hence the error.

You can get your desired output using list slicing:

In [193]: d1 = {'key1': [1,2,3], 'key2': [4,5,6]}
In [194]: d1['key2']
Out[194]: [4, 5, 6]

In [195]: d1['key2'][0::2]  # [start:stop:step]
Out[195]: [4, 6]

Thanks for answering. I am getting different idea. d1['key2'][0:3] also works fine. – VIgnesh Nagaraj Apr 13 '19 at 10:39
@VIgneshNagaraj No, that won't work; `d1['key2'][0:3]` on current example will get you `[4]`. – heemayl Apr 13 '19 at 10:42
But that worked.Can you please check it – VIgnesh Nagaraj Apr 13 '19 at 11:08
