I don't know if I fully understand your question but I hope this helps.

I didn't use a pivot table. I simply cleaned the data from 1st pic then decided I wanted to compare cases in Italy and US so I created a cleaner data (pic2) containing only US and Italy from all the other countries in pic 1.To get that graph, I simply highlighted the new data set and selected a graph from "recommended charts".

I mostly use pivots when I want to select maybe "Top Ten Salesmen" from a hundred sales men then add slicers to select by region,by product or any other category. I hope this helped. Apologies for the unclear pics. I was in a rush.
thanks for the immediate response. However bro, I might stress you abit, but not to worry, answer when convenient for you. First question : please what steps did you take in cleaning the data? Then another question I want to ask, I actually downloaded the finished covid 19 file you uploaded here and tried studying it because I was confused on how to tackle the analysis. But did you select the countries individually from the picture 1, then create a chat for them individually on different worksheets. Was that how you did it for each and every country? I. E, selecting each country from picture one and moving them to a worksheet to analyze each of them separately? Don't know if you understood me. Thanks in advance.

I'm at this stage too.. Currently I just scour freelance sites, register with them and see what sort of jobs available that matches your skills to an extent.. Customise your profile to fit those jobs and apply for them.. I'm registered only on upwork tho and so far no jobs yet but mainly because I am not that serious. I hope this helps

Thanks...

It really did help

Guys,
I just finished my machine learning course.
I learned regression and classification algorithms like SVM, Linear/logistic regression,Random forest, Decision Trees,k nearest neighbor, gradient boosting and co.
Also I learnt unsupervised learning too, and also cross validation,grid search and com
I've also practiced on kaggle too.


Please, what next??

Not one course though.
I used IBM data science course and University of Michigan data science course (both on Coursera) and I also used Jose portilla's machine learning course on Udemy.

I almost smashed my old system (pavilion dv6000) cos of MySQL installation, MySQL workbench wasn’t among the packages download and I tried to do that manually but to no avail but now that I’ve changed my system to a 64 bits, the installation was super easy for me.

Please guys, I am using Microsoft Excel 2010 with no power query add-in and I have data in a text file I want to transform and import to excel. How do I go about this?

PS. I have a Power BI desktop installed on my laptop and I have queried google if I can export to Excel but it seems one can only export dashboards.

I have an issue with this dataset.
I am working on predicting bank loan default.
The dataset consist of three different csv file.
The first one contains the demographics of the data, the second contains previous performance on loans and the third gives information on the loan I'm predicting on.

The issue is that the customers have taken many loans previously and the information of all the previous loans are in the second datasets.

When I merged it, it only took one previous loan information from the second dataset.


How would I merge them such that my new merge would have information on all previous loans?

Thanks in advance.

PS:I'm using PANDAS.

is the text file in csv format? And you want to work on it in excel. If so, go to data ribbon, from text, import text file, leave it on delimited ( characters such as commas or tabs separate each field), next: it will ask you to qualify your delimiter, unclick tab and click the delimiter in your document ( the delimiter could be tab, space, comma, semi column) then click on finish. I guess this is what you should do, if it doesn't work bro, the senior men in the house will have to help you out.

Do you use join, concatenation or merge
If join, you have specify the columns it will join along with.
df = first_data.join(second_data["specify each colunms it will bring along to the table])
