Python and Ubuntu

[newbieAuggie2019]

Hi!

As part of my ongoing quest for a colourful world:
https://python-forum.io/Thread-colouring-strings

it seemed that my problems were due to work on Windows, so I decided to give it a try at Ubuntu, although I always thought that Linux, Ubuntu and the like were for those who already knew how to program.

Well, I managed to install Ubuntu for Windows, and as I'm a completely newbie to Ubuntu, I'm not sure if that means that Ubuntu has all the capabilities, or just the ones provided by Windows and then I'll have the same problems as before ...

I tried to use Python on bash, but while on Windows cmd prompt, python appears like this:

where it says that my version is Python 3.7.4.

On bash, on the contrary:


if I type python, it says 'Command 'python' not found', but that I have 'python3 installed', so I typed python3 and then it said that my version is Python 3.6.7, not Python 3.7.4. So now I have a few questions:

1) Why is that?
2) Shouldn't be the same Python I'm using with Windows?
3) Is it a version pre-installed in Ubuntu?
4) How can I use my Python 3.7.4 and all the little programs that I've made on Windows, now on Ubuntu?

Sorry for bothering you again.
All the best,

A) Ubuntu is considered the noobs of the linux world. A lot is done for you. It is an easy distro for people from windows because you dont have to do much to maintain it.
B) Most linux distros come with python preinstalled as python runs things in linux (unlike windows)
C) Python 3.7.4 is your windows python version while Python 3.6.7 is your default linux python version. If you want to use a newer version on linux you would have to install it under linux.
D) Ubuntu on windows is installed under the windows operating system. So the path to the linux root drive should be somewhere around here
C:\Users\<windows.username>\AppData\Local\lxss\home\<ubuntu.username>\

Although i usually completely delete Windows off my HDD and install a linux distro over top of it. It appears you might want to be careful between modifying files on "Ubuntu for windows" as it could lead to file corruption. An example is window line ending are "\r\n" while unix is "\n"

E) If i want bash abilities on Windows, i just install Cygwin and put its bin directory in my windows path to execute everything in the command prompt.

Thanks a lot! That answers most of my questions.

That means that I can have access from Ubuntu to my python files on Windows?
And vice versa?

Yeah, I'm dealing with many new things and if I involuntary disable my computer, I wouldn't know how to fix it later on.

E) If i want bash abilities on Windows, i just install Cygwin and put its bin directory in my windows path to execute everything in the command prompt.

I'll have a look, but you just mentioning 'bin' and 'path' gives me shivers ... More chances for me to make serious damage to my computer ...

Thanks again, and all the best,

I couldnt promise anything. I have never used Ubuntu for windows. Worst case scenario is you corrupt a python file moving it back and forth. It would be worth a try for sure.

Putting Cygwin bin directory in the path is optional. It is only if you want to open a command prompt and execute bash commands inside a windows cmd. Otherwise you just double click the Cygwin exe and it opens up its own terminal. I just prefer to use the system temrinal/cmd. Its not that hard. This is for XP, but the process stays the same basically across windows 10. All you add is this line to windows path variable ;c:\cygwin\bin and your done. This is how to add to Win 10 path. IN windows 10 add this c:\cygwin\bin assuming that is where you installed cygwin to.

You have cmder as i showed you in an other Thread @newbieAuggie2019.
Then you do not need to mess with Cygwin as cmder has all tool build in.
Try ls,cat,git,ssh,find..ect commands you will see that it work.

Hah! Cmder even has a dd. :D
Just checked.
I am using it from a while but didn't know that. Nice!

Can I use it to make a live USB as on Linux system?

Thanks a lot for your links to how to set paths!!!

I visited the cygwin page, but just the appearance of the page is so unappealing to me, that I think I'll pass on that one ...
I'm a very visual person, so I've kept on investigating and I think I was gearing more to something more appealing like:

It seems that you can even have an image as the background.
I managed even to change now my Windows OS Build from Windows 10 (1803), version number 10.0.17134 to Windows 10 (1903), version number 10.0.18362, as it was the minimum system requirements for the free new Windows terminal, that according to their hype:

"[The] Windows Terminal is a new, modern, fast, efficient, powerful, and productive terminal application for users of command-line tools and shells like Command Prompt, PowerShell, and WSL."

and as usual, they lied about the requirements of installation, they asked for a lot of free space in my C drive, for later asked me for a huger amount of space to use while my Windows 10 was going to be upgraded ... It took about 2 hours at least!!! and of course, they lied too saying that my files were going to be untouched ... Some little old programs I had, have dissappeared completely, and as I needed even more free space on my C drive, now some programs I moved have stopped working too!!!

Try ls,cat,git,ssh,find..ect commands you will see that it work.

I haven't used any of those commands, as I don't know much yet. Thanks a lot for the link!

By the way, I'm using Cmder as the output terminal, that is to say, to see on it the output of the programs I write (by opening a new file with the Python 3.7.4 Shell and writing and saving them there). Can I use Cmder for writing Python programs? If the answer is affirmative, how???

You have cmder as i showed you in an other Thread @newbieAuggie2019.

Yes, I know, and I thank you a lot for it, and as you can see in my colouring strings thread, I've been using it since you recommended it to me. I thought though that still didn't manage to display styles of formatting (like 'bold' or 'italic', that I really want), so I was also checking other alternatives, and I found out that with Cmder, you can use an image as a background, something that I didn't know ... Look at my Cmder now!!!:









Hooray! Now I only miss the formatting styles I want ...

Hah! Cmder even has a dd. :D

What's a dd?

Thank you all, and all the best to everybody,

I must be getting old. A plain black terminal is beautiful to me.

I must be getting old. A plain black terminal is beautiful to me.

Not only beautiful but over the years my brain has developed 'banner-blindness' and quite efficiently ignores everything which it (almost subconsciously) considers 'attention grabber by visual'.

I use customisation for taking away all what I consider 'noise'. As I am not by any means 'terminal heavyweight' I use hyper on macOS.
