本文介绍了使用Python实现无限循环及通过条件判断控制循环流程的方法。包括如何利用while true进行无限循环，并通过计数变量count控制循环退出；还展示了如何在循环中使用continue和break控制流程；最后给出了一个猜年龄的小游戏示例。

while true:

无限循环语句

break跳出循环，当count=1000的时候结束循环



count是结束当前循环
'''
count = 0
while True:
    print("count:",count)
    count = count +1  #count +=1
    if count == 1000:
        break
'''
'''
for i in range(0,10):
    if i <3:
        print("loop ",i)
    else :
        continue
    print("hehe...")
'''

for i in range(10):
    print('----------',i)
    for j in range(10):
        print(j)
        if j >5:
            break





age_of_oldboy = 56

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
else:
    print("you have tried too many times..fuck off")
