# WHAT I LEARNT

## Icecream bug



I've been using "**icecream**" for a couple of days now, exclusively on "replit.com" though.  

When I pip installed it on my new virtual environment (anaconda) on VScode, **it installed it but I couldn't use it**.  



So I searched for a solution on Claude.ai, on Google (reddit and github) and after going back and forth like that for a long couple of hours, **I found the solutions**.



Turns out there are packages ready and available in Anaconda (I forgot about that), and "icecream" is installed from one of them: the forge package.  

The thing is "icecream" is installed with other modules, like "executing" (I know, strange name for a module, right?).  



So, **"icecream" needs to be installed from the "forge package"**, using this command `conda install conda-forge::icecream` **BUT** this does not install "executing" from that same package.  

And it  resulted in installing an **obsolete version of "executing"**. 



The solution was to **initially install it from the forge package too**:  `conda install conda-forge::executing`. 



I wrote a comment in the github page (links below) where they helped me figure this out. I wrote it because no comments was really relevant to my specific case.

## Passing a List through Functions



These 3 short exercises were part of the chapter 8 related to **Functions**.  



When passing a list through functions the `.pop()` method comes handy (*line 43*). It takes out a value from the list and also **permits the assignment of it to another variable.**

The `remove()` or `del` methods do not permit it. 



Then, the `.append(message_out)` method actually moves the value to the new list, iteratively through a "while" and a nested "for" loops (*lines 40 and 41*).

## How did I Do?



The author of the book from which I got these exercises made the solutions available online (links below).  So **I was able to check my work** and see if I did well or not, and that could potentially improve or explain my mistakes. 



Turns out I did pretty well, my code is not a true 100% copy of the solutions as it is now but essentially it is, at around 95% I'd say, **with tiny improvements on my parts, IMHO**.  



I think **my version has a better readability**, due to:

- **comments that are referencing a numbered list** of comments (helps in rolling out the code via a split screens layout when someone else is having a **first read** on it)

- my variable name '**message_out**' is to me better than what the solutions suggest: 'current_message'

- my **function declaration has 1 parameter instead of 2** in the solutions. This **does not make the code more obscure**.

- on line 41, instead of a default placeholder (_) I initially used 'message' but the problem is that it'd be unused anyway. **So using the underscore _ signals that. **



### Commits & Branch



Because I didn't need to correct my work I didn't need to branch out on my github repo.  

So I just did commits on the exercises until I finished them.
