Maybe we don't need object-oriented programming (OOP) in a first-semester computational modeling course

babys-first-functions.py

# Here's a dictionary literal with data and behavior in one line of code
baby1 = {
    "first_function": lambda x: x + 1,
    "first_words": "Zoiby want to buy on margin"
}

# Here's a much more complicated OOP solution in 5 lines
class Baby:
    def __init__(self, first_function, first_words):
        """
        Make a baby
        """
        self.first_function = first_function
        self.first_words = first_words
baby2 = Baby(lambda x: x + 1, "Zoiby want to buy on margin")

baby1["first_words"] # Zoiby want to buy on margin
baby2.first_words # Zoiby want to buy on margin
