An example of an AI chatbot conversation about Python collections vs arrays.
What are the differences between collections and arrays in Python?
In Python, arrays are fixed-size and store elements of the same type, while collections (like lists, sets, and dictionaries) are more flexible and can store mixed types.
Can you give examples of when to use collections over arrays?
Sure! Use lists when you need an ordered collection of items, sets for unique items, and dictionaries for key-value pairs.
Are there performance differences between using collections and arrays?
Yes, arrays are generally faster for numerical operations due to their fixed size and type, while collections offer more flexibility but can be slower for certain operations.
How do I convert a list to an array in Python?
You can use the array module: from array import array and then create an array with my_array = array('i', my_list) for integers.
