First, you must install ortools package in this colab.

python

%pip install ortools

Rabbits and Pheasants quizz.

python

from ortools.sat.python import cp_model


def rabbits_and_pheasants_sat():
    """Solves the rabbits + pheasants problem."""
    model = cp_model.CpModel()

    r = model.new_int_var(0, 100, "r")
    p = model.new_int_var(0, 100, "p")

    # 20 heads.
    model.add(r + p == 20)
    # 56 legs.
    model.add(4 * r + 2 * p == 56)

    # Solves and prints out the solution.
    solver = cp_model.CpSolver()
    status = solver.solve(model)

    if status == cp_model.OPTIMAL:
        print(f"{solver.value(r)} rabbits and {solver.value(p)} pheasants")
