Venvs Part 8 - Folder Structures Continued

So the venv doesn't install a lot of the Python standard library modules. Instead, these get pulled from the global Python's core installation packages, I believe. "Your virtual environment reuses Python's built-ins and standard-library modules from the Python installation you used to create your virtual enviornment." "In a later section, you'll learn how the virtual environment achieves linking to your bas Python's standard library." Okay then.

I'm not really sure how it does that. But yes. Thank you. Basically, doing this speeds up the installation of new environments as it makes the virtual environments more lightweight. It means that we do not have to copy all of the standard Python packages into the new virtual environment. You can add more arguments to the creation of your virtual environment to give it access to the base installation's site packages - OKAY THEN BRO WHAT ARE THOSE. The site packages folder is where Python installs third-party libraries by default. Global site packages are the site packages directory of your system (or "base") Python install. It says "a virtual environment is basically a folder structure with a settings file." Um, okay then.

Whatever that means. Whatever. It says here of the venv that:

"It may or may not come with pip preisntalled, and it has access to the source Python's standard-library modules while remaining isolated." And now the tutorial goes into this all further. Your venv can import global packages from the main Python folder - but not vice versa. I literally give up on this. I will move on to the next section

Okay so what's next then? The next section is called "How does a virtual environment work?" I still haven't gotten onto the coding stuff yet, which is slightly concerning. But it has been a good lesson

Hello World

 Hello from Susanna Codes! Hi everyone,  My name is Susanna and I'm a 28-year-old aspiring software engineer from Brighton! As I type this, listening to music from "Le Fabuleux Destin d'Amelie Poulain" (it reminds me of home, in Luxembourg, where I am from - I'm missing home quite a lot lately!) and look forward to some Irish Cream tea in my afternoon break, I am thinking: How lucky I am that my amazing colleague Rosana helped me out with a plan for my software engineer journey (she directed me to the front-end first). How HTML and CSS would not have been my first languages of choice had I not been guided in this direction, as in my head they were seen as 'less-serious' langages. How done I am with what other people think of me and if other people see the 'front-end' as softer then so be it! Everyone has to start somewhere. I am so grateful to be on this journey, with Codecademy's Front-End Engineer Career Path.  Thank you to Async Brighton as ...

“But yesterday, I heard God say, you were born to be the one…”

“But yesterday, I heard God say, you were born to be the one…” Hey there. Still off work. Still tired. Lana del Rey released a new song. Thank God. My soul needed it so much.  I’m thinking a lot about everything. Thinking about where I went wrong. I just want to release. I want to release all the crap that is in my room. I’ve been trying to fully declutter since I was 21. I give away so much. I donate so much. But then I never quite finish. I never get to the click. And then I buy more. I don’t know what technique to use. There are so many techniques. The Marie Kondo method. I like to do kinaesthetic tests too. I like to pretend I’m packing up during the pandemic again and I have to make really quick decisions about what to keep and what to leave behind. That was no fun. But it was efficient. I just can’t release it. There’s so much stuff I can’t let go of. I don’t know how to. I don’t know how to. I suppose that’s a good metaphor for life. We accumulate stuff and we hold on to it....

In the Water, I find Fire

In the Water, I find Fire Who am I without renewable energy? I had to ask myself this question last year when my company laid off half its employees.  I didn’t know who I was anymore. Not without renewable energy. But I did everything I could to stay in it. The time in between jobs allowed me to experiment. Travel around the UK a bit. Reconnect with old hobbies. Rediscover my femininity a bit - be someone who wasn’t always working. But I fought to stay in renewable energy. A part of myself has been telling myself that I am in renewable energy still and that’s great because I am. But I am mostly in water. And that was hard for me to accept that. Because I love renewable energy so so much. And I couldn’t imagine my life without it. But now I can. Not because I don’t love it But because I need to give myself to something more too and that is water Because in the water I find my passion In the water, I find my fire In the water, I find my self again In the water, I find my Self So let’...
