Part 7 - Venvs folder structures

Part 7 - Venvs folder structures

I ran a command and there was a huge tree. I have no idea what I'm doing anymore but I used pip list. I've just learned that there are some other packages installed by default too. The tutorial lists them nicely. Aha! It says here:

"YOUR VIRTUAL ENVIRONMENT IS JUST A FOLDER STRUCTURE, WHICH MEANS THAT YOU CAN DELETE AND RE-CREATE IT ANY TIME YOU WANT. Can confirm - the amount of times I have been told to nuke my virtual enviornment as a solution 

Have just been obscene 

This tutorial says:

But why this specific folder structure, and what does this structure make possible?

Oh Jesus Christ almighty. I have never been so last as this before. Let's keep on going. 

"An Isolated Python Installation"

"Python virtual environments aim to provide a lightweight, isolated Python environment that you can quickly create and then discard when you don't need it anymore." That makes sense.

"The folder structure that you just explored makes that possible by providing three key pieces:" 
  1. A copy or symlink of the Python library
  2. A pyenv.cfg file
  3. A site-packages directory
"You want to achieve an isolated environment so that any external packages you install won't conflict with global site-packages." 
  • "To make this possible, venv reproduces the folder structure that a standard Python installation creates."
  • "This structure accounds for the location of the compy or symlink of the Python binary and the site-packages directory, where Python installs external packages."
Oh Jesus Christ almighty. That sounds very hard indeed. Well it's 6 pm

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’...
