Why not just use just convert it to a numpy array and easily use indexing rather than these loop statements.

I know, I'm just giving you an easier alternative... You'll still use numpy alot as you progress, so it's better you start getting used to it now.

All of the rows or just one. If just one which one?

If you want to get all of the rows, do this

for row in matrix:
print(row)

Thank you @paapi3d and all contributors for the support, i have been following up with this thread's videos and instruction

Please am a beginner in python and it's IDE. I have downloaded python as well as visual studio IDE as instructed

However, the challenge am having now is how to integrate python into the visual studio environment so i can start coding

Secondly, can i use visual studio IDE for data analysis?

Please any one in the house to assist? your feedback will be much appreciated�

I am more interested in using python for datascience so the best environment for me is Jupyter notebook launched on my chrome browser. The best IDE you can work in python for other purposes like web development using Django, Modeling, and building Modules is pycharm. You can download the cracked version from getintopc.com. Windows don't come with python preinstalled so you have do download and install the python version you want from the web, after install you need to copy the path where your python was install and paste it in the environmental variable path. Save and you are good to go with calling python from the cmd, pycharm or any IDE of your choice. There are plenty videos on YouTube that can help you with this. Cheers

can I send u a dm

Hello loiusdthird, am sorry for responding to you this late. I'm just a beginner (python) programmer and I haven't even be steady sef. I'm after a lot of back and forth and trying other stuffs just trying to settle on Python.
Yesterday night, I tried running "Hello world" on sublime but the message wer I see eh, have been on it since yesterday night till this morning.

However, if you still want to contact me, you can go ahead. I'm even looking for a learning partner sef because this journey is not easy to even go solo.
I have some materials i can also share with you.

So I tried running "hello world" yesterday night but I keep getting this message:

[WinError 2] The system cannot find the file specified
[cmd: ['python3', '-u', 'C:\\Users\\Okporghe\\AppData\\Roaming\\Sublime Text 3\\Packages\\User\\Python3.sublime-build']]

What could be the problem and possible solutions??

What are you trying to do? Are you trying to run a python script through Sublime text? If yes, how did you install Python on your system?

I believe you should type the following:

for rows in items:
# To print the second row
if items == matrix[1]:
print(rows)

Yes I'm trying to run a python script through Sublime TE.

I installed Python from the site. 3.9, the latest version.

I've even edited the new build system in Sublime TE.

First ensure python is working on your system.
1. Go to your list of installed apps, look for Python 3.9 IDLE, launch it. If it opens up go to step 2.
2. Go to your command line, or simply click on Run then type in cmd. At the command line prompt type in python then press enter. If you get an error, type in python3 the press enter. If you get an error again, then it is very likely you did not add your python installation to the Windows PATH variable.

Perform the tasks above, then let me know the outcome.

Run 'python --version' from terminal to check if python was properly installed

following

I m following a Python tutorial using Visual studio code on udemy. i only have the main code area on top, i cant get the two lower windows setup and the guy uses it a lot. How can i do it ? see my page

Just toggle your terminal, press ctrl + shift + p, then in the search bar, search for "toggle integrated terminal" and click on it

And seems your tutor is using Bash with vs code. So you'll need to install Bash and add the path to VS code settings.json, then toggle your bash terminal as I've described above.

You can also make use of your command prompt terminal if you are confused of what I've said above

Semtu:

I've done that and it was properly installed.
I now use VS code and Pycharm.

Meanwhile, some of the Udemy courses I downloaded have some videos in them that do not play, play for a while and stops and have no sound.
What could be the problem and possible solutions??

Algorithmic Trading with Python – Free 4-hour Course With Example Code Repos

While I have tried Udemy paid and free. I got much solace in www.educba.com They have all the courses listed and have about 100projects (solved) that you can re-use as yours. The videos are well detailed and suitable for all newbies irrespective of your level. It is an all in one inclusive course that covers all courses and just all you need to be proficient in data analysis, analytics and visuals. The projects are what would convince anyone about your knowledge of subject and get you up and running. Incidentally, *Educba* is the largest site in Asia and like we all know, the Indians are excellent on this. I feel you should consider the free resources.

They have free samples you could test. Should you wish to get the course, I can help you with a *blackhat coupon* code to save you cost.

DM me to learn more.

I believe you should type the following:

for items in matrix:
for rows in items:
# To print the second row
if items == matrix[1]:
print(rows)

And this is cleaner

matrix = [
[1,2,3],
[4,5,6],
[7,8,9]
]

for i, items in enumerate(matrix):
if i ==2:
print(matrix[i])


if you want to print every item of the 3x3 matrix, do this

for i, items in enumerate(matrix):
for i, value in enumerate(items):
print(items[i])
