python 学习 字符串拼接、整数序列求和、九九乘法表输出、计算1+2！+3！...+10！、猴子吃桃问题 、健康食谱输出的结果 红五角星DAY11

1、字符串拼接

getwords1 = input("请输入国家名字：")
getwords2 = input("请输入首都名字：")

print("您输入的是："+getwords1+getwords2)

2、整数序列求和

getNum = eval(input("请输入数字："))
s = 0
for i in range(getNum+1):
    s = s + i

print(s)

3、九九乘法表输出

for i in range(1,10):
    for j in range(1,i+1):
        print(" {0}*{1}={2} ".format(i,j,i*j),end='')
    print('\n')

 4、计算1+2！+3！...+10！的结果

s ,p = 0,1
for i in range(1,11):
    p = p*i
    s = s+p

print(s)

5、猴子吃桃问题

def f(n):
    if n == 1:
        return 1
    else:
        return (f(n-1)*2+2)

print(f(5))

6、健康食谱输出

diet = ["西红柿","鸡蛋","土豆","茄子","豆芽"]
s = []
for i in range(0,5):
    for j in range(0,5):
        if not(i == j):
            print("{}+{}".format(diet[i],diet[j]))

7、红五角星

import turtle
turtle.setup(800,600,200,200)
turtle.pencolor("red")
turtle.fillcolor("red")
turtle.speed(10)
turtle.begin_fill()
while True:
    turtle.fd(200)
    turtle.right(144)
    if abs(turtle.pos()) < 1:
        break
turtle.end_fill()
turtle.hideturtle()

turtle.done()
