A classic case of how to use Python to realize chicken and rabbit in the same cage

This article mainly explains "how to use Python to realize the classic case of chicken and rabbit in the same cage". The content of the explanation in the article is simple and clear, and it is easy to learn and understand. please follow the editor's train of thought to study and learn "how to use Python to realize the classic case of chicken and rabbit in the same cage".

I. Overview of the problem

Chickens and rabbits in the same cage, a total of 30 heads, 88 feet, how many chickens and rabbits are there?

Second, train of thought

Except that chickens are rabbits, let the number of chickens and rabbits be equal to the number of heads, n, the number of feet be f, the number of chickens be x, and the number of rabbits be y.

Y = n-x

2x + 4y = f

If you satisfy the above equation, you can know how many chickens and rabbits there are.

Third, code implementation

Def chicken_rabbit (npene f): for x in range (1jie n + 1): y = n-x if 2 * x + 4 * y = f: print ('chickens have {}, rabbits have {}' .format (xpeny)) chicken_rabbit has 16 chickens and 14 rabbits thank you for your reading.
