How to identify dependencies between elements of a list?

Question

Python

Suppose there is a list [24, 22, 81, 4, 72, 2355, 2, 3, 2358],
How to check that there is a relationship between its elements? (sum, difference. product..)
Ie . 24 * 3 = 72
2358 = 2355 + 3?

Answer 1

Inefficient solution

from itertools import combinations
import operator

operators = [
    (operator.add, "+"),
    (operator.mul, "*"),
    (operator.sub, "-"),
    (operator.truediv, "/")
]

numbers = [24, 22, 81, 4, 72, 2355, 2, 3, 2358]

for n1, n2 in combinations(numbers, 2):
    for oper in operators:
        result = oper[0](n1, n2)
        if result in numbers:
            print("{}{}{}={}".format(n1, oper[1], n2, result))

Answer 2

Answer 3

First, you need to choose a model and a learning algorithm. Then train the model, check the quality, and finally identify the pattern. It is advisable to check the revealed patterns, and if it is not correct, start over.
