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. I hope the above content can be helpful to you so that you can learn more knowledge. If you think the article is good, please share it for more people to see.
