Hi, I am having some serious difficulties on this exercise. I think I got it ok for the 1st part, but I am stuck on the 2nd part. Open the file and differentiate headers from values with def_parse functions was ok, but then I am completely lost. I tried different things to create a list with the values from the file’s columns, but all brought me to errors that I was not able to solve (I’m a python beginner). I don’t know how to approach the problem anymore, can someone guide me on this please ?
I have to correct this post because today I’m starting with https://jovian.ai/learn/data-analysis-with-python-zero-to-pandas/lesson/lesson-3-numerical-computing-with-numpy, maybe you should try to check this lesson before trying the exercise, i think the numpy library will provide you a better way to solve the exercise than the code above, anyway i’m leaving it, it may help you to understand the logic to create the dictionary.
Hi Miguel, thank you for your responses, indeed I am doing the exercise with close attention to the lesson 3. However I still can’t figure out how, and I m not sure I understand all the steps of your code. I am experiencing two struggles here, the first one with the logic, the second one with the right syntax.
The way I see it is first to define what a header is and what a value is, so far ok. Then, I would like to define 4 lists which would represent the 4 different columns (without the headers), and then include them into a dictionary, with the headers being the 4 different keys, and the 4 columns being the values of the dictionary. Please let me know if the logic makes sense, if it’s possible to do it this way, if it’s a good way to do it, and if so, how can I do it. Thank you very much for your help !
Hello again Quentin,
I,m posting here a notebook with the new code I wrote for the exercise, the previous code was confusing and impractical. This one includes the Numpy library to solve the problem. I have not finish the last step of the exercise and there are no explanations of the code for the moment. Anyway for each step there is a printed output in order to understand them better.
Hi Miguel, thank you again for your response. I’ve been through the file and it indeed helped me a lot to understand and solve part 2 and 3. I’ve also included some intermediate functions. Now doing part 4 but already having some obstacles… Anyway, if you want to have a look, here below is my code so far:
