总结
1.键盘猜三次数字
import random
r = random.randrange(1,99)
i=0
for x in range(3):
n = int(input('请输入1--100内的两位数：'))
if n==r:
print('恭喜！你猜对了！')
break
elif nr:
print('你猜大了！')
i+=1
if i==3:
print('不好意思，机会完了！')
2.循环输入五个数字，求平均值
i=1
s=0
while i<=5:
n=float(input('请输入数字：'))
if n<0:
print('输入为负，程序结束')
break
s+=n
i+=1
if i==6:
print('平均数为：',s/5)
3.珠穆朗玛峰叠纸
h=0.01
i=0
while h<=8848:
h*=2
i+=1
print('需要折叠次数：',i)
4.小芳存钱
s=0
i=0
while s<=100:
i+=1
s+=2.5
if i%5==0:
s-=6
print(i)
