如何处理附加在 windows 生成的 csv 末尾的空行？

Question

I wrote a function to deal with the null values in the csv before passing it to a forecasting model

if do_nulls_exist == True:
    print('found a null value')
    null_rows = pd.isnull(data)
    print('######### ORIGINAL ROWS THAT NEED UPDATING ##############')
    print(null_rows)
    # Need to add 2 to each value in null_rows because there

    print('######### ROWS + 2 = ACTUAL ROW NUMBERS IN CSV ##############')
    update_these_rows = []
    for x in null_rows:
        update_these_rows.append(int(x)+2)

    print(update_these_rows)

    emit('error', {'data': update_these_rows})

As you can see the there is a null row appended at the end (Row no 36)

Pls guide me as to how I can remove this null row. Thanks!

Before passing CSV to forecast model you can apply dropna() function on Dataframe. It will delete all null row's

    df = df.dropna()
