Question

由于缺乏清晰度，我重复了我的问题。下面的代码得到一个随机数，然后检查它是否是一个新的高，并记录它是否是一个。然后经过一定的延迟（1分钟）后，它会再次从前一个时期的最后一个数字开始做同样的事情。

我想以不同的频率运行相同的所以我将有很多句号，如果我在函数中重写下面的代码，例如，我可以得到agregateinfrequency（5min），它将只返回下面的打印（或列表）< / p>

希望现在更有意义。

for random_number, current_time,i in generator():
    previous_last_price = mynumber
    mynumber = mynumber + (random_number*0.0001)
    #print (random_number*0.01)
    if mynumber >high_price: #new one
        high_price = mynumber
    if mynumber <low_price: #new one
        low_price = mynumber
    last_price = mynumber

    if keyfunc(current_time,1) != previous_reftime1min: #new one
        print mynumber,",",i, current_time,",", keyfunc(current_time,1),",", previous_reftime1min,",", open_price,",", high_price,",", low_price,",", last_price
        wrtr.writerow([mynumber, i,current_time, keyfunc(current_time,1), previous_reftime1min, open_price, high_price, low_price, last_price])    
        myfile.flush() # whenever you want, and/or
        open_price = previous_last_price
        high_price = mynumber
        low_price = mynumber
        last_price = mynumber
        previous_reftime1min = keyfunc(current_time,1)

以下是基于我理解你想要它做什么的脚本可能结构的一些伪代码。

def check_price(random_number,last_price):
  new_price = do_some_logic() #do your logic
  write(new_price) #some abstract code to write your output to a file
  return new_price

price=some_initval
  while True:
    g=get_new_random_number()
    price=check_price(g,price)
    sleep(desired_period)

我没有使用for循环，而是在这里使用while循环。我的理解是，您打算将此程序用作连续运行的守护程序，每分钟左右醒来，检查一些数据（例如当前价格）并运行计算。 while True确保程序将重复执行此操作，直到您将其删除为止。
