python if/while/fo条件判断

判断3次，猜年龄

方法一

 1 # author = "zhuyouen"
 2 age_of_zhuyouen = 35
 3 
 4 count = 0
 5 while count < 3:
 6     guess_age = int(input("age:"))
 7     if age_of_zhuyouen == guess_age:
 8         print("age is ok")
 9         break
10     elif age_of_zhuyouen > guess_age:
11         print("age is small")
12     else:
13         print("age in large")
14     count +=1
15 else:
16     print("you have test too many times,fuck off..")
D:\python35\python.exe D:/PycharmProjects/zhuyouen/0324/guess.py
age:35
age is ok

方法二

 1 # author = "zhuyouen"
 2 age_of_zhuyouen = 35
 3 
 4 for i in range(3):
 5     guess_age = int(input("age:"))
 6     if age_of_zhuyouen == guess_age:
 7         print("age is ok")
 8         break
 9     elif age_of_zhuyouen > guess_age:
10         print("age is small")
11     else:
12         print("age in large")
13 else:
14     print("you have test too many times,fuck off..")
D:\python35\python.exe D:/PycharmProjects/zhuyouen/0324/guess_for.py
age:23
age is small
age:23
age is small
age:35
age is ok

方法三

 1 # author = "zhuyouen"
 2 age_of_zhuyouen = 35
 3 
 4 count = 0
 5 while count < 3:
 6     guess_age = int(input("age:"))
 7     if age_of_zhuyouen == guess_age:
 8         print("age is ok")
 9         break
10     elif age_of_zhuyouen > guess_age:
11         print("age is small")
12     else:
13         print("age in large")
14     count +=1
15     if count == 3:
16         confirm_input = input("do you want input guess again..")
17         if confirm_input != "quit":
18             count = 0
D:\python35\python.exe D:/PycharmProjects/zhuyouen/0324/guess任意.py
age:1
age is small
age:1
age is small
age:1
age is small
do you want input guess again..quit
