Python常见程序

1，求水仙花数

1.for i in range(100,1000):
    s=str(i)
    if int(s[0])**3+int(s[1])**3+int(s[2])**3==i:
         print(i)

2.for bai in range(1,10):

    for shi in range(10):
        for ge in range(10):
            x=bai*100+shi*10+ge
            if x==bai**3+shi**3+ge**3:
                print(x)

3.for i in range(100,1000):

    bai=i//100
    shi=i%100//10
    ge=i%10
    if i==bai**3+shi**3+ge**3:
        print(i)
2.倒序输入一组数据

str=input("请输入一串字符:")
for i in range(len(str)-1,-1,-1):
    print('%c'%str[i],end='')

3.冒泡算法

score=[56,77,89,43,29,98,76,55,8,34,79,234,88]
print(score)
n=len(score)
for i in range(0,n-1):
    for j in range(n-1,i,-1):
        if score[j]<score[j-1]:
            score[j],score[j-1]=score[j-1],score[j]
print(score)

4.求5的阶层

def f(number):
    if number==1:
        return 1
    else:
        return f(number-1)*number
print(f(5))

5.打印九九乘法口诀
for i in range(1,10):
    for j in range(1,i+1):
        print('%d*%d=%d'%(j,i,j*i),end=" ")
    print('')
