It's the second day of the Jump Start that took place two days ago. After the talks about the If and Nested If statements, there came the Lists, file reading, opening and writing along with appending as well as the For and While loops in which I had already done those before in the Coursera course of Python programming last time which was Introduction to Interactive Programming in Python. However, the difference between the course I took and the Jump Start was likely to be the programming tool you're using as well as the way you make use of the other files. From the online progarmming tool I used as part of the Coursera course, the files were pretty much part of the cloud technology but there's no way to access them easily through the File Explorer-like interface where you can look at the folders and files along with the different kinds on the window. Just think of the Windows Explorer or anything similar to that when accessing those kinds of files but I don't think there's such kind of interface at Coursera lest you end up accessing other students' work and then tempering with it using that interface. Another difference is that some of the topics were not common in between this Jump Start and that Coursera course. So, when it came to making use of the external files, writing and appending to files as well as reading them with the use fo the code, I don't think it might be exactly the same kind of coding in that Coursera course.
The last module from the Jump Start was about handling errors. You might have seen the occurance of those errors from the pervious modules and how the errors could have been fixed with the help of the advices and hints that were shown to you throughout the Jump Start. Also, they can be found on the slides which were available for download. But in case you have missed the Jump Start or something, you should be able to jump into it and get the presentations from there at the MVA website provided that it should be available two weeks after it took place live.
Lastly, I still have yet to do the challenges but with the help of that Coursera course I took, it should still be a challenge but I don't know if I can clear those challenges with enough meanings until I try.
