## Ice-breaker Activity

:question: Name one thing you learned about Python in the class preparation and why do you think it's useful? :snake: 


- mutable and immutable.
- classes example and how it was structured so different kinds could communicate with each other.
- dir function was helpful.
- loops for linear algebra.
- dictionary: when to use [], (), and {}?
    - list:
        - create a list: `a = [1,2,3]`
        - get an element in the list: `element = a[0]`
    - dict:
        - create a dict: `d = {'name': 'Alessandro', 'age': 15}`
        - get an element in the dict: `element = d['name']`
- variables and functions and loops syntax was interesting and easy-to-use due to similarities to MatLab syntax
