curl - class Sessions, regex : re lib

Inspirations:

• D03 Ex03 de la piscine django [le sujet ou une solution]
• Un workshop d'Harvard (très bien fait) [static ou jupyter notebook]

Global notes:

Reverse 00 and 01

ex00:

• 1. Add real prototypes of the functions

ex01

• 1. Add ERROR in doom_printer
• 2. ObjectC has to be modified
• 3. talk about setattr ?

ex02

• 1. add cat machine log
• 2. missing print("Blub blub blub...") at the end of function "add_water"

ex03

• 1. read a csv instead of a json
• 2. handle missing file
• 3. turn in directory: ex00

ex04

• 1. turn in directory: ex00
• 2. tell to rename
• 3. bash build.sh && pip install ./dist/42ai-1.0.0.tar.gz
• 4. package name : ai42

Noticed the pdfs are ~8mb which is a lot for a text file, and sometimes slow to open: I suggest to compress them with any free online tool.
For instance here
Cheers! 🐍

in ex00 of day01,
If the idea is to reuse the dictionnary of ex06 in day00, in order to match the meal types between the 2 exercises, the 3 keys in recipes_list (dict) of ex00 day01 should be "starter", "lunch", "dessert" instead of "starter", "main_course", "dessert"

To avoid misunderstanding (the forbidden func of this exercice is 'None') add Forbidden library : Numpy

"You will also be able to install packages via pip using this script."
Vous voulez dire qu'on devrait par le même installer.sh pouvoir appeler pip ? Selon quelle syntaxe ? Tout argument qui n'est pas "install-python" appelle pip3 [mon_argument] ?

For divisions,
in Python3 it seems there is no operator such as div and rdiv, it should be truediv and rtruediv instead

https://docs.python.org/3/reference/datamodel.html

Dans l'énoncé, on demande "a function that takes 2 numbers as parameters" mais on ne sait pas comment traiter les float (si par exemple on essaye python operations.py 10.5 3). Perso, je considère qu'on attend 2 int en paramètres :)

MIT license covers this software and associated documentation files but the repository only contains documents. Also one could argue sparse pieces of source code in these documents is not software.

You may consider using a Creative Commons license like CC-BY-SA.

And why not tell that included source code is in public domain so anyone can use it? In a tutorial, source code will be copied without following the license, so better to ease the task legally.

If you include pdf build scripts, these indeed will be software though.

We have really bad feedbacks concerning this exercice we have to change it to make it simpler

from_shape(shape, value) : une variable taille et une valeur.

La valeur par default dans le prototype.

==> from_shape(shape, value=0) : une variable taille et une valeur. ()

Notions:

• basic setup
• variables (types)
• fonctions (retourne tuple)
• loop
• main
• import
• data struct
• list
• dict
• list comprehensions

• Day: 04
• Exercise: 07

Maybe it would be necessary to add visual examples (pictures of plots) and to write shorter explanations.

https://docs.conda.io/projects/conda/en/latest/user-guide/install/macos.html

In the outputs:

npc.from_iterable(range(5)) should be on a new line

"You have handle the error if the arg passed in add_recipe is not a recipe."
->
"You will have to handle the error if the arg passed in add_recipe is not a recipe."
On the last line of the ex00 desciption

"...and also to keep the first line as header is headers is True."
Seems it should be:
"...and also to keep the first line as header is True."

$> python exec.py "Hello World!"
   !DLROw OLLEw
   $> python exec.py "Hello" "my Friend"

Global notes:

• ex04 is simpler than ex03

ex00:

ex01:

ex02:

• 1. Is it necessary to handle errors?
• 2. Drop duplicated values and update the result in the example (0.02307969707897584) to 0.01935634328358209.
  See: #5 (comment)

ex03:

ex04:

• 1. The examples are a bit misleading: sp.where(2162) is not in the dataset and sp.when('Atlanta') olympic games took place in 1996, neither in 1903 nor 2042.
  It should be mentioned not to trust the examples.
  See: #5 (comment)

ex05:

• 1. If duplicated medals are not handled for the team games, this exercise is too similar to ex03.
• 2. The CSV data is not up-to-date.
• 3. Precise in the instructions if duplicated medals per team games should be handled and add an example from the dataset.
  If duplicated medals are dropped: France 2008: {'G': 25, 'S': 24, 'B': 28} -> {'G': 7, 'S': 16, 'B': 20}
  See: #5 (comment)

ex06:

• 1. Add concrete examples:
  Maybe add some plots (mathplotlin.pyplot.hist()) screenshots for more clarity. All images must be put in an assets directory at the root of the day folder.
• 2. The word feature from ML and data science terminology can be a little bit confusing at the beginning.

ex07:

• 1. Add concrete examples:
  Maybe add some plots (mathplotlin.pyplot.hist()) screenshots for more clarity. All images must be put in an assets directory at the root of the day folder.

Global notes:

• 1. PDF title says Day01 instead of Day03

ex00:

ex01:

• 1. Filename for ex01 is "imageProcesor.py", it should be "ImageProcessor.py"

ex02:

• 1. the "crop" function, "dimensions" is an ambiguous name. It should be instead called "new_image_size" and the exercise should ask for error handling if new_image_size.width > initial_img_size.width etc
• 2. "mosaic": rename "dimensions" "grid_size"
• 3. more example and error management
• 4. "thin(array, n, axis) : delete every nth pixel along the specified axis (0 vertical, 1 horizontal)" ; shouldn't it be "delete all pixels except every n-th pixel along..."
• 5. explain more in descriptions of the functions

ex03:

• 1. to_{color} functions are mismatched: function name is never the same as the filter in the description
• 2. autoriser arange ou linspace
• 3. grayscale: no example given for a custom weigth vector: should I understand it should always be 0.299R + 0.587G + 0.114B ?

Global notes:

ex00

• 1. Error management not a recipe
• 2. self.last_update when adding recipe
• 3. add import recipe
• 4. "Recipe" class : naming attributes or arguments like keywords is bad practice ('type'=>'recipe_type')
• 5. doc python in french link
• 6. get_recipe_by_types(self, [recipe_]type)
• 7. def get_recipe_by_name(self, name): """Print a recipe with the name 'name' """ more precisions

ex01

• 1. add a double inheritance ? #2 (comment) ==> create a new issue asking for an addon

ex02

• 1. Bad practice 'len' instead of 'length' attribut
• 2. constructor rule not clear "range"
• 3. radd etc..
• 4. mul == dot product

ex03

• 2. sep=" " should be mandatory remove the name of arg
• 3. Error management for bad string

ex04

• 1. new exercice

ex05

• 1. Need a testing file
• 2. 'origin' en anglais, pas 'origine'

• Day: 00
• Exercise: 00

Hi,
In the Conda automated install topic, there is this line :

echo "export PATH=$MINICONDA_PATH:$PATH" >> ~/.zshrc

The thing is that if you have a PATH like:

/bar:/my/folder/with space/:/foo

the sourcing will fail because of invalid format of the variable (it expands environment variable).
Replacing double quotes with single should resolve this issue.

Hope it helps !

Edit:
My bad, it creates other issues.

But escaping the $ of $PATH should resolve the issue.

Le sujet nous donne :

function prototype

def generator(text, sep=None, option=None):
'''Option is an optionnal arg, sep is mandatory'''

The sep argument is noted as sep=None which in my understanding contradict
the statement that "sep is mandatory".

Also, optionnal => optional

• Day: 00
• Exercise: 03

Apparently some confusion on what text_analyzer should do when the number of arguments is greater than 1.

Examples
text_analyzer("this is the first sentence.", "this is a second sentence.").

"Write a program to display the string above right-aligned with '-' padding and a total length of
42 characters: "

L exemple d'output donne pour "python kata03.py | wc -c" donne 42 pour resultat
me semble incorrect, selon moi le resultat attendu devrait etre 43 (42 char + \n)

➜ ex05 python kata03.py | cat -e
--------------------------The right format$
➜ ex05 python kata03.py | wc -c
43

Je ne suis pas sur de moi sur celle la mais je vous invite a check

First assign your self to the related issue.

In order to create content for the piscine you will have to create a branch with the following template : day/XX/phaseY
(where XX is the number of the day and Y the related Phase)

The day folder will have the following architecture :

└── day00
    ├── day00.md
    ├── ex00
    │   └── ex00.md
    ├── ex01
    │   └── ex01.md
    └── ex02
        └── ex02.md

Turn-in directory is set to ex00 instead of ex01 on the .pdf.

add
radd

add : scalars and vectors, can have errors with vectors.

sub
rsub

sub : scalars and vectors, can have errors with vectors.

truediv
rtruediv

div : only scalars.

mul
rmul

mul : scalars and vectors, can have errors with vectors,

return a scalar **is ( >> if )**we perform Vector * Vector (dot product)

str
repr

Dans l'exemple, la même ligne de commande donne 2 comportements différents:

$> ./installer.sh install-python
[v] python is installed.
$> ./installer.sh install-python
Python is already installed, do you want to reinstall it ?

In the subject it s written : • length : size of the vector
But length seems to be "number of coords in vector"
Thank you

D'ou sort Loadjson ?
Sous class de CsvReader ?

from csvreader import CsvReader
if name == "main":
with Loadjson('good.csv') as file:
data = file.getdata()
header = file.getheader()

python exec.py "Hello" "my Friend" | cat -e

'w' instead of 'h'

We have to create a list a of general rules and add them to all day[xx].md files.

day03 ex02:permorm; did you mean perform ?

day03 ex03: "(.arange ?)" qui flotte dans le doute

day04 ex06: pourrait avoir des page-end afin de mieux organiser les diagrammes et leurs titres

day04 ex07: "BONUS: Your functions can also accept a list of numerical variables, and output comparison plots for each feature against different"...

Dans l'exo 10 du day 00, il est demandé de faire une fonction ft_progress(list). Mettre list comme nom de variable redéfinie le nom built-in list.
