Hi, I keep having error with my try-except code. Is like basically every date in the revision_timestamp returns an error.
This is despite me converting the column to a date_time and then string format to make the API call ready for comparison.
The date displayed on the screenshot are outside the date range included in the API call function.

Ok. I checked for just two articles. Should I check for all the articles in order to know whether there is any data available for all the revision_timestamps of different articles? And what if no data is available for the dates mentioned in revision_timestamps?

I manually set the start and end dates for the year 2022 for two articles just to check whether my code is displaying the page views count or not and it did display the counts. But the task was to fetch start and end dates from revision_timestamps, so when I modified my code accordingly, it didn't fetch data and displayed the above error message in the screenshot. Is there data available for the dates mentioned in revision timestamps?

Here is the screenshot.

When I manually set the start and end dates for the year 2022, it displayed the page views count for that time frame but when dates are fetched from revision_timestamps, it displays no data available and prints the error message.

Hello Everyone, I'm getting an error after running the try except block. I've tried implementing other codes and have also tried to change the start and end dates as well as article names. But still, the issue persists. Any help here would certainly enhance my task completion, Thank you.

I modified the code but then it gave this error

Then I visited the link in error message and this was displayed for two articles named Albedo and Agriculture

The error happens when there is no data at that timestamp. Use a try and catch block as suggested by others above.

I have already included a try-except block in the code which is printing the error message.

When I use the start and end dates from revision timestamps for fetching the pageviews count for articles, it's giving the following error. Please help.

Hey @Satoshi_Sh, would you share the full link to `python-mwviews/src/mwviews/api

/pageviews.py`

Hello Everyone!!
I'm stuck with a Key error of 'revision_timestamp' column. As you all might get to know the dataset contains this column, still its throwing an error. I have tried printing column names but still, the output didn't print this column.

can anyone plz help me a bit about this or anyone got the same issue ?

I'm not 100% sure unless I check your whole notebook, but does that "df" data frame contain the "revision_timestamp" column? You might have another data frame.

You can double-check it with something like this.

`# Check dataframe columns
columns =df.columns
print(columns)`

yeah, I checked it several times and it shows that the column exists in the same dataframe.
Did you proceed to task 2 and got any errors with revision_timestamp column?

I will highly appreciate your assistance in this.

Hi Shreyash,

This is the source code from `python-mwviews/src/mwviews/api
/pageviews.py`. I believe they don't have any available data within your selected timeframe. That's why you get the error message. You can try another timeframe. Hope this helps your question.

try:
           results = self.get_concurrent(urls)
           some_data_returned = False
           for result in results:
               if 'items' in result:
                   some_data_returned = True
               else:
                   continue
               for item in result['items']:
                   output[parse_date(item['timestamp'])][item['project']] = item['views']

           if not some_data_returned:
               raise Exception(
                   'The pageview API returned nothing useful at: {}'.format(urls)
               )
           return output

Yes , I understood it . Thank you

are you able to get passsed the error? @ASHreyash7

Hi @Thembo42
The error occurs when certain timeframes lacks pageview count, Hence the API might raise an Exception in such case.
You need to handle such cases to get passed this error.
Hope this helps.

By handle, do you mean to choose a timeframe where all rows have a view count?

It should work if it has at least one data/row in your timeframe.

Yes, I understand that. I'm saying should we choose a granularity that just works, or we should choose (say hourly) and scan through the year to check for data because @ASHreyash7 was saying something like check for test cases. Should we check for test cases or simply choose another granularity-this is what I don't understand. Thank you.
