python循环练习

1、打印5以内不重复的三位数

count=0
for i in range(1,5):
for j in range(1,5):
    if i == j:
        continue
    for p in range(1,5):
        if i == p or j == p :
            continue
        count+=1
        print("%d%d%d " %(i,j,p))
        print("%d" %count)

2、求最小公倍数和最大公约数

while True:
a=int(input("please input first num:"))
b=int(input("please input second num:"))
Min=min(a,b)
Max=0
if Min == 0 :
    print("no gong yue shu")
else:
    for i in range(1,Min+1):
  	      if a % i ==0 and b % i == 0:
            Max =  i

        else:
            continue
print("zui da gong yue shu wei:%d" %Max)
print("zui da gong bei shu wei:%d" %(a*b/Max))

3、猜数游戏

import random
i = 0
count = 0
while i < 100:
    Random = random.randint(1, 100)
    num = int(input("please input a num:"))
    num = 10
    if num > Random:
        i += 1
        pass
    elif num < Random:
        i += 1
        pass
    else:
        count += 1
        i += 1
print (count)
