The Imitation Game, part III

I'm still listening to the soundtrack. Still living my best life...

A photo from the film "The imitation game" - a character (name unknown) stands next to a quote that says "Sometimes it's the people who no one imagines anything of who do the things that no one can imagine."

What does Python classify as mutable?

"A mutable object refers to various containers in Python that are intended to be changed."

"A list for example has append and remove operations that change the elements of the list."

"Sets and dictionaries are also two other mutable objects in Python AS THEY CAN BE CHANGED ON THE FLY". 

"Some objects in Python are not mutable, and THEREFORE ARE OKAY TO BE USED AS DEFAULT ARGUMENTS".

From the official documentation

"Default parameter values are evaluated from left to right when a function definition is executed. This means that the expression is evaluated once, when the function is defined, and that the same "pre-computed" value is used for each call." 


What on earth does this mean? I don't understand it!!! One thing I learned during my AI in renewable energy research is to not just parrot stuff. I have to write out what I think things mean for myself. Eeeek - ooooh...

What do I think this means

Oh wait Codecademy has some more definitions. 

Let me start with this - phew.

"When we call a function, the default values we provide for parameters are only created oncem abd used for each subsequent calls of the function.

And now they introduce "None". But my brain is overwhelmed. I need to get not too bogged down with stuff and not too stuck on stuff. I need to keep on going...

I'm sad

I've been trying to buy some raw honey.

Went to the Polish shop and bought some honey for £12.50. In my desperation I wanted it to be raw. Now I'm not sure if it was raw. Oh well - still wondering...

Hold on - I have a test that I know that I can do to check... let me do it after work...

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

Yosemite

Yosemite I'll never forget the first time I head the song Yosemite by Lana del Rey. I very nearly clicked away.  It was quite near the start of my Software Engineering journey, right near when I start learning the Front-End/Web Development. I was listening to Arcadia by LDR before, maybe twice, and then Blue Banisters came on. I nearly clicked away in the first 30 seconds but I forced myself to keep listening anyway.  I'll never forget how that song has made me feel. It became my song of 2022 even though I only discovered it in November. I can still listen to it every day and get that complete sense of wonder and of awe that I felt the first time that I heard it. That ending of the song is completely amazing, and it just completely just blows me away every time. "Withstanding all the time, changes, and seasons..." - LDR Concise Body Arrow Functions Why am I so bad at arrow functions? Whyyyyyyyyyyy?  Just kidding, I am beginning to get them. But why are they so hard? &

Two Lines of Thought, Makes Me Wonder What I'm Missing

Two Lines of Thought, Makes Me Wonder What I'm Missing "Lines of Bamboo, See What You Do To Me..." Bamboo by Elder Island is one of my ultimate 'becoming a Software Engineer songs'. (I prefer the original, but here is a great live version. ) There's a story behind this. I met a man named Mark. He was an SWE approaching retirement - he was down in my hometown with his wife, visiting. I won't go into the context of how we met, but it was a miracle. It was a complete miracle. It was just meant to be. We chatted for at least two hours and at the end of the conversation he said to me "All the best of luck with your new career". I couldn't believe what he'd just said - I hadn't even committed to it yet! A few weeks later, I did, though. After I walked out of that cafe where I had been sitting and talking to Mark and his wife though, I felt like - even though I didn't "feel ready" yet - Mark had predicted something that I didn&
