    Hi Harish,

    I'm stuck with sets, one of the example you gave in class did not work for me. While creating a set, you gave an example below

    a = [10,1,2,2,3,4,5,5,5,7]
    set1 = set(a)
    print(set1)

    I just copy pasted the same code and executed it but it is returning an error which says set object is not callable. Please review this..
    Attaching a screenshot for your reference.

    Hi Harish,
    I was not able to access the Google drive because it is asking for app downloading option which is not supporting in my laptop.

    What can be the alternate to have access for the same.

    Please let me know.

    regards
    Prateek

    Hello,

    While splitting the array I was getting an error.

    new_cyclist_trials= np.array([[10,15,17,26,13,19],[12,11,21,24,14,23]])
    np.hsplit(new_cyclist_trials, 2)

    And I got an error as below:

    "
    ---------------------------------------------------------------------------
    TypeError Traceback (most recent call last)
    <ipython-input-319-8a446b3e1d8b> in <module>
    ----> 1np.hsplit(new_cyclist_trials, 2)

    TypeError: 'tuple' object is not callable

    print(ratings_df.head())
    It has been returning an error

    Hi Daniel,
    The Google Drive Link is working smoothly and I have checked it on my end. You might be using an
    incomplete or incorrect link.
    You can refer the updated link below.
    # Google Drive Link - Harish - DS with Python :
    https://drive.google.com/open?id=1tq2zQD5-QGKLwGSiDQudaL2wtEGJfrYD
    Also, for your second query, I checked your code and it is fully correct and is working smoothly on
    my end. I recommend you do delete and re-download the dataset and then try reading it again.
    # Screenshot : attached
    I hope that this will help you.

    Hi all,

    I got a task.
    I have to provide a service that should read CSV files from a FTP/azure storage.
    The service must read files dynamically from this location and then clean up the data. ( cleaning conditions are already defined). How to create a service?
    We need to provide the cleaned data in some way, ( maybe in NoSql/mango db etc)
    How to do this? What will be the best way and how to do this?

    Thank you in advance.

    Hi Saju,

    We are really sorry to say that we do not cover the Azure database and NoSql database in Data Science with Python Course. It is a cross-domain.
    We are unable to answer this question.
