When should I use dictionaries in Python?

Dictionaries are great for storing data in key-value pairs. Use them when you need fast lookups, like counting occurrences.

Can you give me an example of when to use a dictionary?

Sure! If you want to count the frequency of words in a text, a dictionary can map each word to its count.

What are the advantages of using dictionaries over lists?

Dictionaries provide faster access to values via keys, while lists require searching through elements, which is slower.

Are there any downsides to using dictionaries?

Yes, dictionaries use more memory than lists and are unordered, so if order matters, consider using a list or an ordered dictionary.
