练习——week 1

• 三元运算符
  最大数

a = float(input('请输入第一个数：'))
b = float(input('请输入第二个数：'))
c = float(input('请输入第三个数：'))

my_max = a>b and a or b
my_max = c>my_max and c or my_max
'''
my_max = a
if my_max < b:
    my_max = b
elif my_max < c:
    my_max = c
'''
print('最大数为：',my_max)

• 元组
  从小到大输出

a = int(input('请输入第一个数：'))
b = int(input('请输入第二个数：'))
c = int(input('请输入第三个数：'))
if a>b:
    a,b = b,a
if b>c:
    b,c = c,b
if a>b:
    a,b = b,a
'''
(a,b) = a>b and (b,a) or (a,b)
(b,c) = b>c and (c,b) or (b,c)
(a,b) = a>b and (b,a) or (a,b)
'''
print(a,b,c)

2到100之间的素数

for i in range(2,101):
    is_prime = True
    #判断是不是素数
    for j in range(2,i):
        if i%j==0:
            is_prime = False
            break
    if is_prime:
        print('%d是素数'%(i))

    print()

A,B,C,D,E五个人捕鱼后已凌晨，大家便睡觉。早上A第一个醒来，将鱼均分成五份，把多余的一条鱼扔掉，拿走自己的一份，B第二个醒来，也将鱼均分为五份，把多余的一条鱼扔掉，拿走自己的一份。CDE依次醒来，也按同样的方法拿鱼，问他们合伙至少捕了几条鱼。

fash = 1
while True:

水仙花数 1m3+5m3+3m3=153

for i in range(2,1000):
    if (i//100)**3+(i%100//10)**3+(i%10)**3 == i:

找出10000以内的完美数
完美数：除本身外所有因子和等于本身

from time import time
from math import *
star = time()
for i in range(1,10000):
    num = 1
    for j in range(2,int(sqrt(i))+1):
        if i%j==0:
            num += j
            if j!=i//j:
                num += i//j
    if num==i:
        print(i)
end = time()
