Hello pros in the house. I have a quick question. For about 3 weeks now, I've been getting familiar with data science and analysis using python and tableau. over the week, I've gotten really comfortable with python basic programming and done lots of simple projects online while simultaneously learning tableau and PowerBi also. I am now in the data analysis part of python using pandas, numpy, seaborn and matplotlib but it's seeming a little difficult. I've also gotten very comfortable with tableau for data analysis and I'm thinking of mastering Tableau and PowerBi for like a month while I leave python pending. I'll come back to python though after I must have mastered tableau and PowerBi. What do you guys suggest please?? 1 Like |

I beg o, I have a question. How can I group countries by continents? Mind you, I created the excel file myself and I used sublime to convert the csv file to unicode-8. My suspicion is that my code is right but my formatting is wrong. However, when I run a groupby code: covid.groupby('continent').TotalCases() it generates a KeyError: 'continent' I think it is the way I formatted my file. I wanted to ask the gurus how they did it. Update I previously asked about how to generate a barplot. I got some inputs but I had to find the solution myself. This tiny graph here...it is automated. No cutting of corners-which is the whole essence of coding. I took me 4 days to plot this, it is tiny but I am proud of my achievement. Next is plotting a stacked histogram based on continents. Tablue and powerBi, I am coming to humble the both of you. I will must learn this data science thing by force. plot of covid cases from countries with more than 15k cases. 2 Likes

RealTrump:The result you posted shows that the error is not from the code, but from the continent, try changing the continent to "Continent" capital letter C. 1 Like 1 Share |

Ejiod:Experts in the house please help see to this issue, I just pip installer Numpy, Pandas and jupyter so as to start learning using Pandas for analysis, I opened a new folder stores the file to be processed, navigated to the folder through the CMD prompt and launched jupyter from there. But to my surprise I was not able to import the file until I went on YouTube and saw a video where he added (encoding, "Latin" nrows=(number of rows) I tried it and it worked but I don't understand jack about what I did and why I had to add the encoding in order for the file to be imported on jupyter notebook. Secondly have been going through some Pandas videos online and 80% of the analysis have seen can be done using excel it Dax function in PowerBI, can someone highlight the important and unique things used during preparing a file for analysis in platforms like PowerBI. Also, I have been seeing videos where they use Pandas for analysis where they extract useful information from a file for example determining countries with over 5000cases of Corona virus from a dataframe, after getting this separate info, how can this information be stored separately? Also I'd like to know for those using matplotlib, after getting the visuals what next? Do they export the graph? Generally I just want to know how they gather findings together in Pandas for purpose of reuse or continuation of analysis in other platforms. Pardon my questions I am inquisitive by nature at things I don't know. God bless you for answering

KunSegzy100:https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.read_csv.html read for more infor u can also use # df1 = pd.read_csv('train.csv', engine='python') it will fix de problem 1 Like |
Re: Chronicle Of A Data Scientist/analyst by Ejiod(m): 11:35am On Apr 11, 2020 |
KunSegzy100:Most time it’s advisable to point your pandas to the directory so it reads it not via the cmd. Press Tab + I to see the documentation of the read_csv 1 Like |
Re: Chronicle Of A Data Scientist/analyst by gargoylern: 12:01pm On Apr 11, 2020 |
KunSegzy100: different files have different encodings, due to the way they are prepared. The encoding for that file apparently is not the default in pd.read_csv. Sometimes you have to guess the encoding, sometimes they tell you so you know. You shouldn't be too worried about encoding at this stage. Secondly have been going through some Pandas videos online and 80% of the analysis have seen can be done using excel it Dax function in PowerBI, can someone highlight the important and unique things used during preparing a file for analysis in platforms like PowerBI. You store it in another dataframe. You can create as many dataframes as you want as you go along. As a beginner, this may not be a problem. But as you advance, you'll realize the importance of saving memory or managing memory, so you'll be able to work better with dataframes. Also I'd like to know for those using matplotlib, after getting the visuals what next? Do they export the graph? Generally I just want to know how they gather findings together in Pandas for purpose of reuse or continuation of analysis in other platforms.Yes, you export the plot. After importing Matplotlib.pyplot as plt, you can use plt.savefig() can save your plots and export them as pictures to other platforms.

Ejiod:sir @ Ejiod I have been following this trend since last year, am inspired by your work and what you are doing in this trend am a data scientist and also analyst, but am finding it hard to get a job, am an undergraduate @ UNN. Most companies I have applied for said that u have to be working there full time and are not remote. I need your advice on what to do. If one have a skill and is not using it to make money its discouraging. 1 Like 1 Share |

Evanspaul:I understand your point. Dear now you understand the in and out of data science. My advice is for you to complete your program 1st. Add web development skills to it. Try learning JavaScript,HTML or CSS. Use the web development skills and apply too. Most firms wants full time not part time or remote. It’s only startups that would give you a remote option. Lastly apply to upwork. 6 Likes |
