What interesting cases are there in Python?

This article will explain in detail what interesting cases there are in Python. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

I. description of the problem

Kakatani of Japan put forward a conjecture, the content of which is:

For any natural number, repeat the following operations:

(1) if it is odd, multiply it by 3 and add 1

(2) if it is an even number, the result 1 can always be obtained by dividing it by 2.

Second, train of thought

The following calculations are made repeatedly through the loop:

Let the natural number be n

1. If n takes the remainder 2, odd, then n = * 3 + 1

2. If n does not take the remainder 2, even number, then n = n / 2

III. Code

Def jiaogu (n): N1 = n while N1! = 1: N1 = N1 * 3 + 1 if N1% 2 else N1 / 2 print about "what are the interesting cases in Python?" this article ends here.
