练习题
2.1.编写以一个python程序来查找那些可以被7除以5的整数的数字，介于1500到2700之间。
t = 1500
for i in range(1500, 2700): if i % 7 == 0 and i % 5 ==0:print(i)t +=1
2.2.龟兔赛跑
v1,v2,t,s,l = map(int,input().split())
if v1<=100 and v2<=100 and t<=300 and s<=10 and l<=10000 and l%v1==0 and l%v2==0:s1,s2,i = 0,0,0while s1<l and s2<l:s1,s2,i=v1+s1,v2+s2,i+1if s1==l or s2==l:breakelif s1-s2>=t:s2,i=s2+v2*s,i+sif s1>s2:print('R')print(i)if s1==s2:print('D')print(i)if s1<s2:print('T')print(int(l/v2))
3.猜数字游戏
import random #random库主要用于产生各种分布的伪随机数序列，使用random库的主要目的是生成随机数
Set_number = random.randint(0,100)
print(Set_number)
Guess_number = int(input("请输入："))
N = 1
while(Guess_number < Set_number or Guess_number > Set_number):N = N + 1if Guess_number > Set_number:print("太大")elif Guess_number < Set_number:print("太小")Guess_number = int(input("输入错误"))
print("恭喜你猜到了这个这个数是".format(N))
