在 for 循环中尝试/除外 while true

Question

The following code will gather data from an API and the try/except clause will help to handle several errors (from authentication, index, anything). There's only one error (an authentication error) that I'm using the while True to repeat the API call to make sure I get the data and it will after a try or two. However if by any means I get another error, it'll be infinitely looping and I can't break it so it goes to the next iteration. I tried to create a counter and if the counter reaches to a number then ( pass or continue or break ) but it's not working.

## Create a array to loop to:
data_array_query = pd.date_range(start_date,end_date,freq='6H')

#This is my idea but is not working
#Create a counter
counter = 0

#Loop through the just created array
for idx in range(len(data_array_query)-1):
    ## If counter reaches move on to next for loop element
    while True:
        if counter>=5:
            break
        else:
            try:
                start_date  = data_array_query[idx]
                end_date = data_array_query[idx+1]

                print('from',start_date,'to',end_date)

                df = api.query(domain, site_slug, resolution, data_series_collection, start_date=str(start_date), end_date=str(end_date), env='prod', from_archive=True, phase='production').sort_index()
                print(df.info())
                break
            except Exception as e:
                print(e)
                counter +=1
                print(counter)

So the output of running this code for a couple of days show that when it runs 5 times (that's the counter max I set up) it does break but it breaks the whole loop and I only want it to move to the next date.

Any help will be appreciated,

You need to use a break statement to get out of a while True loop. pass and continue work for for loops that have a fixed number of iterations. While loops can go on forever (hence the different names)
