如何用python编写简单的代码?

这篇文章包括用Python编写的斐波那契数列,三位数的水仙花数和百钱买百鸡的基础代码
一、斐波那契数列:
'''
def hanshu(n):
n_1 = 1
n_2 = 1
m = n
sumn = 0
for a in range(1,m+1):
if m == 1:
return n_1
if m== 2:
return n_2
sumn = n_1 + n_2
n_2 = n_1
n_1 = sumn
print(sumn,end = " ")
hanshu(20)
'''
二、找出1-1000之内的水仙花数:
def hanshu(n):
sumn = 0
m = n
for dix in range(1,4):
m = m % 10
sumn = sumn + m ** 3
m = n // 10
if sumn == n:
print(n,end = " ")
def hanshu1():
for b in range(1,1000):
hanshu(b)
hanshu1()
三、百钱买百鸡:公鸡5元一只,母鸡3元一只,小鸡0.5元一只,100块钱买100只鸡
问:应该买多少只公鸡母鸡和小鸡,一共有几种买法
设:公鸡为x只,母鸡为y只,小鸡为z只
x = 0
while x <= 100:
y = 0
while y <= 100:
z = 0
while z <= 100:
if x + y + z == 100 and 5 * x +3 * y +0.5 * z == 100:
print(x,y,z)
z += 1
y += 1
x += 1
