Adding Spotify Data from zenodo in a DataFrame

I want to add all the data from charts.zip from https://doi.org/10.5281/zenodo.4778562 in a single DataFrame. The data consist of a file per year that contains multiple CSVs. I made the following code:

header = 0
dfs = []
for file in glob.glob('Charts/*/201?/*.csv'):
    region = file.split('/')[1]
    dates = re.findall('\d{4}-\d{2}-\d{2}', file.split('/')[-1])
    weekly_chart = pd.read_csv(file, header=header, sep='\t')
    weekly_chart['week_start'] = datetime.strptime(dates[0], '%Y-%m-%d')
    weekly_chart['week_end'] = datetime.strptime(dates[1], '%Y-%m-%d')
    weekly_chart['region'] = region
    dfs.append(weekly_chart)
all_charts = pd.concat(dfs)

But, when I run it, python returns:

---------------------------------------------------------------------------
ValueError                                Traceback (most recent call last)
/tmp/ipykernel_12886/3473678833.py in <module>
      9     weekly_chart['region'] = region
     10     dfs.append(weekly_chart)
---> 11 all_charts = pd.concat(dfs)

    310                 )

    402         if len(objs) == 0:
--> 403             raise ValueError("No objects to concatenate")
    404 
    405         if keys is None:

ValueError: No objects to concatenate

How can I fix it?

Prop `className` did not match in next js app

I have written a sample code ( Github Link here ). this is a simple next js app, but giving me error when I refresh the page. This seems to be the common problem and I tried the fix provided in the internet but does not seem to fix my issue. The error is Warning: Prop className did not match. Server: "MuiBox-root MuiBox-root-1" Client: "MuiBox-root MuiBox-root-2". Did changes for _document.js, modified _app.js as mentioned in official website and solutions in stackoverflow. but nothing seems to work. Could someone take a look and help me whats wrong with the code? Via Active questions tagged javascript - Stack Overflow https://ift.tt/2FdjaAW
