-  \item The version of Python recommended to use is 3.7, you can
-  check the version of Python with the following command: \texttt{python -V}
-  
-  \item The norm: during this bootcamp, it is recommended to follow the
-  \href{https://www.python.org/dev/peps/pep-0008/}{PEP 8 standards}, though it is not mandatory.
-  You can install \href{https://pypi.org/project/pycodestyle}{pycodestyle} which
-  is a tool to check your Python code.
-  \item The function \texttt{eval} is never allowed.
-  \item The exercises are ordered from the easiest to the hardest.
-  \item Your exercises are going to be evaluated by someone else,
-  so make sure that your variable names and function names are appropriate and civil.
-  \item Your manual is the internet.
-  
-  \item If you are a student from 42, you can access our Discord server 
-  on \href{https://discord.com/channels/887850395697807362/887850396314398720}{42 student's associations portal} and ask your

-  
-  \item We encourage you to create test programs for your
-  project even though this work \textbf{won't have to be
-  submitted and won't be graded}. It will give you a chance
-  to easily test your work and your peers’ work. You will find
-  those tests especially useful during your defence. Indeed,

-\chapter{Common Instructions}
-\begin{itemize}
-  \item The version of Python recommended to use is 3.7, you can
-  check the version of Python with the following command: \texttt{python -V}
-  
-  \item The norm: during this bootcamp, it is recommended to follow the
-  \href{https://www.python.org/dev/peps/pep-0008/}{PEP 8 standards}, though it is not mandatory.
-  You can install \href{https://pypi.org/project/pycodestyle}{pycodestyle} which
-  is a tool to check your Python code.
-  \item The function \texttt{eval} is never allowed.
-  \item The exercises are ordered from the easiest to the hardest.
-  \item Your exercises are going to be evaluated by someone else,
-  so make sure that your variable names and function names are appropriate and civil.
-  \item Your manual is the internet.
-  
-  \item If you are a student from 42, you can access our Discord server 
-  on \href{https://discord.com/channels/887850395697807362/887850396314398720}{42 student's associations portal} and ask your
-  questions to your peers in the dedicated Bootcamp channel. 
-
-  \item You can learn more about 42 Artificial Intelligence by visiting \href{https://42-ai.github.io}{our website}.
-
-  \item If you find any issue or mistake in the subject please create an issue on \href{https://github.com/42-AI/bootcamp_machine-learning/issues}{42AI repository on Github}.
-  
-  \item We encourage you to create test programs for your
-  project even though this work \textbf{won't have to be
-  submitted and won't be graded}. It will give you a chance
-  to easily test your work and your peers’ work. You will find
-  those tests especially useful during your defence. Indeed,
-  during defence, you are free to use your tests and/or the
-  tests of the peer you are evaluating.
-
-  \item We are constantly looking to improve these bootcamps, and your feedbacks are essential for us to do so !\\
-  You can tell us more about your experience with this module by filling \href{https://forms.gle/Df9hrjBRLv57bALm9}{this form}.\\
-  Thank you in advance and good luck for this bootcamp !

-  
-  \item We encourage you to create test programs for your
-  project even though this work \textbf{won't have to be
-  submitted and won't be graded}. It will give you a chance
-  to easily test your work and your peers’ work. You will find
-  those tests especially useful during your defence. Indeed,
