1、for循環競猜年齡：

age_of_oldboy = 56

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

count = 0
for i in range(3):
    guess_age = int(input("guess age:"))
    if guess_age == age_of_oldboy :
        print("yes, you got it. ")
        break  #結束循環
    elif guess_age > age_of_oldboy:
        print("think smaller...")
    else:
        print("think bigger!")
else:
    print("you have tried too many times.. fuck off..")

2、for循環，continue跳出本次循環
 

for i in range(0,10):
    if i < 3:
        print("loop",i)
    else:
        continue #跳出本次循環，進入下次循環
    print("hehe...")
