python while basic example

1. Loop ten times to exit the while loop:

count = 0
while True:
    print("count:",count)
    count = count + 1  #count +=1
    if count ==10:
        break

2、猜年纪：

age_of_oldboy = 56 

#guess_age = int(input("guess age:")) 

count = 0 
while count<3: 
    guess_age = int(input("guess age:")) 
    if guess_age == age_of_oldboy : 
        print("yes, you got it. ") 
        break #Don't go out of the loop else 
    elif guess_age > age_of_oldboy: 
        print("think smaller...") 
    else: 
        print("think bigger!") 
    count+=1 
else: 
    print("you have tried too many times.. ") 

3. When it reaches 3 times, it will prompt whether to continue the guessing. Enter n to exit:

count = 0
while count<3:
    guess_age = int(input("guess age:"))
    if guess_age == age_of_oldboy :
        print("yes, you got it. ")
        break
    elif guess_age > age_of_oldboy:
        print("think smaller...")
    else:
        print("think bigger!")
    count+=1
    if count == 3:
        countine_confirm = input("do you want to keep guessing..?")
        if countine_confirm != 'n':
            count = 0
