What are Python collections and how are they used in data science?
Python collections are built-in data types that allow you to store and manage data efficiently. In data science, they are used to handle datasets, perform operations, and manipulate data structures.
Can you explain the different types of collections in Python?
Sure! The main types of collections in Python are lists, tuples, sets, and dictionaries. Each has its own use cases and characteristics.
How do I choose which collection to use for my data?
It depends on your needs. Use lists for ordered data, sets for unique items, tuples for immutable sequences, and dictionaries for key-value pairs.
Can you give an example of using a dictionary in data science?
Absolutely! You can use a dictionary to store the results of a survey, where the keys are the questions and the values are the responses.
