python變量引用，while和for循環

一、變量引用
#!/usr/bin/env python
# coding: UTF-8

name = 'xk'
age = 27
job = 'it'
info='''
name: %s
age: %s
job: %s
''' %(name, age, job)
print(info)

==============================================

name: xk
age: 27
job: it

==============================

2、wile循環

#!/usr/bin/env python
# coding: UTF-8


age = 27
count = 0
while count < 3:
    guess_age = int(input("guess age: "))
    if guess_age == age:
        print("you got it!")
        break
    elif guess_age > age:
        print("guess smaller!")
    else:
        print("guess bigger!")
    count += 1
    if count == 3:
        confirm = input("do you want try agein?")
        if confirm != "n" or confirm != "N":
            count = 0
else:
    print("you try too mana times")

3、for循環

#!/usr/bin/env python
# coding: UTF-8

age = 27
for i in range(3):
    guess1_age = int(input("please input your guess age: "))
    if guess1_age == age:
        print("you are good!")
        break
    elif guess1_age > age:
        print("guess smaller!")
    else:
        print("guess bigger!")
else:
    print("mana times!!!!!!!!!!!")
