I was asking about dictionary section…Does sequence of elements in dictionary matters or not

Hi @guptashashank552552,

The sequence of key:value pairs in a dictionary usually don’t matter because unlike lists, we don’t use indices in a dictionary. We use keys to get or set a value in a dictionary.

As your question is unclear, I am not sure whether it helps or not, but here is a post that can help you to understand how can we assign values to an empty dictionary.

Best,
Sahil
