Python 入门编程题：1~10（答案）

提示：最好还是先思考，先编写，再看答案哦 ^_^

1.

for i in range(1, 5):

for j in range(1,5):

for k in range(1, 5):

if i != j and j!= k and i != k:

print(i,j,k)

2.

i = int(input('净利润:'))

arr = [1000000,600000,400000,200000,100000,0]

rat = [0.01,0.015,0.03,0.05,0.075,0.1]

r = 0

for idx in range(0,6):

if i > arr[idx]:

r += (i - arr[idx]) * rat[idx]

print((i-arr[idx]) * rat[idx])

i = arr[idx]

print(r)

3.

import math

for i in range(10001):

if math.sqrt(i + 100) == int(math.sqrt(i + 100)) and math.sqrt(i + 268) == int(math.sqrt(i + 268)):

print(i)

4.

def leapyear(n):

return True if (n % 4 == 0 and n % 100 != 0) or n % 400 == 0 else False

days = [31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30 ]

year, month, day = [int(x) for x in input('input year/month/day: ').split('/')]

day2 = sum(days[:month - 1]) + day

if leapyear(year) and month > 2:

day2 += 1

print(day2)

5.

L = []

a = int(input('请输入第一个整数：'))

b = int(input('请输入第二个整数：'))

c = int(input('请输入第三个整数：'))

L.append(a)

L.append(b)

L.append(c)

L.sort()

print(L)

6.

#斐波那契数列。

def fib(n):

a,b = 1,1

for i in range(n-1):

a,b = b,a+b

return a

7.

#输出 9*9 乘法口诀表

for i in range(1, 10):

for j in range(1, i+1):

print('%s * %s = %s' %(i, j, i * j), end = ' ')

print()

8.

import math

leap = 1

h = 0

for m in range(101, 201):

k = int(math.sqrt(m + 1))

for i in range(2, k+1):

if m % i == 0:

leap = 0

break

if leap == 1:

print('%-4d' %m, end = '')

h += 1

if h % 10 == 0:

print()

leap = 1

print('The total is %d' % h)

9.

from math import sqrt

#判断n是否为素数

def isprime(n):

if n <= 1:

return 0

m = int(sqrt(n))+1

for x in range(2,m):

if n%x == 0:

return 0

return 1

#利用递归分解n并打印质因数

def bprime(n):

if isprime(n):

print(n)

else:

x = 2

while x <= int(n/2):

if n%x == 0:

print(x)

return bprime(n/x)

x = x + 1

10.

x2 = 1

for day in range(9,0,-1):

x1 = (x2 + 1) * 2

x2 = x1

print(x1)
