How to upgrade your python version to 3.7 in ubuntu to avoid problems?

I wanted to download a package some days ago which gave an error 'doesn't contain python>=3.7'; which meant that I didn't have python of versions more than or equal to 3.7. So I went ahead and downloaded and faced certain problems. That's why I am writing this article.

One line work:

The only thing you need to do for this is write in bash:

sudo apt update -y
sudo apt install python3.7

Now this part is important. In many tutorials, you may have seen the following line:


sudo update-alternatives --install /usr/bin/python python3 /usr/bin/python3.7 2
sudo update-alternatives --config python3

Now doing this last line, tutorials will tell you to selection 3.7 as the default option. That is where your system may go wrong. I did the same. And then the following three problem came up:
(1) there is a red circle in notification bar with a white dash inside it. This says, some error happened while checking for updates.
(2) You will not be able to access the software center.
(3) Your terminal will not open.

Now at this point, your terminal path is actually broken as well as the software center. What you need to do if you have already done this and facing one of these problems, is that:

Open the terminal from desktop > right click on open space > select open terminal from list opened > write the following line again in terminal
sudo update-alternatives --config python3


Now choose a version of python less than or equal to 3.6 this time. Then restart your pc once. Then see. The notification circle will be gone; your terminal will start and all the things will be fine again.
Important thing is, your default version will still not be 3.7 or more than that. So when you need to download things or use python 3.7 or so on; please create a virtual environment with that specific python version and then use it.
Thanks for reading! comment below to let me know about anything related to this.

20 Must-Know Math Puzzles for Data Science Interviews: Test Your Problem-Solving Skills

Introduction:   When preparing for a data science interview, brushing up on your coding and statistical knowledge is crucial—but math puzzles also play a significant role. Many interviewers use puzzles to assess how candidates approach complex problems, test their logical reasoning, and gauge their problem-solving efficiency. These puzzles are often designed to test not only your knowledge of math but also your ability to think critically and creatively. Here, we've compiled 20 challenging yet exciting math puzzles to help you prepare for data science interviews. We’ll walk you through each puzzle, followed by an explanation of the solution. 1. The Missing Dollar Puzzle Puzzle: Three friends check into a hotel room that costs $30. They each contribute $10. Later, the hotel realizes there was an error and the room actually costs $25. The hotel gives $5 back to the bellboy to return to the friends, but the bellboy, being dishonest, pockets $2 and gives $1 back to each friend. No...

GAM model : PyGAM package details Analysis and possible issue resolving

Introduction:                  picture credit to peter laurinec. I have been studying about PyGAM package for last couple of days. Now, I am planning to thoroughly analyze the code of PyGAM package with necessary description of GAM model and sources whenever necessary. This is going to be a long post and very much technical in nature. Pre-requisites: For understanding the coding part of PyGAM package, first you have to learn what is a GAM model. GAM stands for generalized additive model, i.e. it is a type of statistical modeling where a target variable Y is roughly represented by additive combination of set of different functions. In formula it can be written as: g(E[Y]) = f 1 (x 1 ) + f 2 (x 2 ) + f 3 (x 3 ,x 4 )+...etc where g is called a link function and f are different types of functions. In technical terms, in GAM model, theoretically expectation of the link transformed target variable is assume...

Pyarabic: python package for Arabic language

 Introduction:  In languages which are non-english and non-european as well, NLP work has progressed slowly in the last few decades because of the lesser number of scholars working on them as well as a lack of global interest in them. But now the time has changed and people from all over the world are collaborating on these lesser explored libraries and they are building resources for working on these languages with the same ease with that of english.  Pyarabic is a package created from such a similar effort which deals with the intricate details of the arabic language and helps processing all kinds of arabic texts. While trying to learn it, being from a non-arab background, I couldn't read lots of parts of the main readthedocs site and had to work my around it. So in this blog post, I will summarize my learnings in english language, so that you can learn it and use the package with much more ease than me. [Credit where credit is due: this article heavily uses the ac...
