how do i open a .ipynb file ? what softwares am i suppose to install to complete the whole course ?

Hi Jorge!
Thanks for reaching out.
Please accept my apologies for the delayed response.
*.ipynb files can be opened with Jupyter. Please consult the following lecture for an explanation on how to install Anaconda which is a software that contains Jupyter within itself. https://learn.365datascience.com/courses/introduction-to-jupyter/welcome-to-the-course Then, please watch the following two videos to learn how to operate with Jupyter. https://learn.365datascience.com/courses/introduction-to-jupyter/welcome-to-the-course https://learn.365datascience.com/courses/introduction-to-jupyter/welcome-to-the-course Hope this helps but please feel free to get back to us should you need further assistance.
