Thanks, wonderful lecture. One question, How you get all the rows as output when run the df, whereas I am getting only first 5 and last 5 records of the data. Kindly explain.
hi, you have to install pandas before importing. In the command prompt type pip3 install pandas. It will get installed. Then you import . for numpy also same procedure
@@akashgoojre846 Go to your windows command prompt and paste "python -m pip install --upgrade pip". After installation type "pip install pandas". --> datatofish.com/upgrade-pip/
i installed just 10days ago everything is installed well without any problem. don't worry try the installation from the beginning....1st unstall it and install it carefully
Have you install all the mention libs. if not then Go to your windows command prompt and paste "python -m pip install --upgrade pip". After installation type "pip install pandas". --> datatofish.com/upgrade-pip/ after this go to your editor and import the mentioned libs. as shown in the video.
Regarding the availability, the course session got recently concluded in April. I suggest that you pls sign up in the portal and check when the next course session commences. As far as the course is concerned it is available free of cost and every week classes are uploaded and an interactive session is also there for doubt clearing (and the student also get some assignments for practice). As time progresses and the course session ends you'll be communicated through mail about exams and it is to your discretion whether you want to take the exam or not(but certification is provided on completion of the final test ). If you register for the exam subsequently you have to pay only for the exam and get the result and certification from NPTEL on fulfillment of the required credits (do check the portal for that ) and a computer based exam is held for which you'll be notified through mail .
Have you install all the mention libs. if not then Go to your windows command prompt and paste "python -m pip install --upgrade pip". After installation type "pip install pandas". --> datatofish.com/upgrade-pip/ after this go to your editor and import the mentioned libs.
go to downloaded file ...right click...copy path....paste in inverted commas df=pd.read_csv('C:/Users/nehab/Downloads/gapminder-FiveYearData.csv') now replace backslash with forward slash
