Python笔记（7）while循环

#!/user/bin/env python # -*- coding:utf-8 -*- # author:berlin #1、while无限循环 # count = 0 # while True: # print("count:",count) # count = count + 1 #count +=1 #循环与if elif else的结合 #1、当等于1000时就终止 # count = 0 # while True: # print("count:",count) # count = count + 1 #count +=1 # if count == 1000: # break # 2、猜年龄正确了就终止 # age = 26 # while True: # getage = int(input("请输入年龄：")) # if getage == age: # print("猜对了！") # break #终止 # elif getage < age: # print("猜小了！") # else: # print("猜大了！") # 3、猜年龄正确了就终止，只能猜三次 # age = 26 # count = 0 # while True: # if count == 3: # break # getage = int(input("请输入年龄：")) # if getage == age: # print("猜对了！") # break # 终止 # elif getage < age: # print("猜小了！") # else: # print("猜大了！") # count += 1 # 4、猜年龄正确了就终止，只能猜三次并提示（while循环的另一种方式） # age = 26 # count = 0 # while count < 3: #第一次从0开始 # getage = int(input("请输入年龄：")) # if getage == age: # print("猜对了！") # break # 终止 # elif getage < age: # print("猜小了！") # else: # print("猜大了！") # count += 1 # if count == 3: # print("你猜太多了！！！！") # 5、猜年龄正确了就终止，只能猜三次并提示（while else方式） # age = 26 # count = 0 # while count < 3: #第一次从0开始 # getage = int(input("请输入年龄：")) # if getage == age: # print("猜对了！") # break # 终止 代表循环判断结束 # elif getage < age: # print("猜小了！") # else: # print("猜大了！") # count += 1 # else: # print("你猜太多了！！！！") # 6、猜年龄正确了就终止，只能猜三次并询问是否继续，若yes则继续，若no则退出循环 age = 26 count = 0 while count < 3: #第一次从0开始 getage = int(input("请输入年龄：")) if getage == age: print("猜对了！") break #continue代表跳出本次循环，执行下一次循环。break代表结束循环 elif getage < age: print("猜小了！") else: print("猜大了！") count += 1 if count == 3: iscontinue = input("是否继续：") if iscontinue == "yes": count = 0 else: print("结束！！") # else: # print("你猜太多了！！！！")
