Summary

Linux

A quick rundown of the most important Linux commands from today's session is:

• ls: list the current directory;

• cd <direcory>: move to the specified directory;

• mkdir creates a new directory;

• touch creates a new file;

• rm deletes files and directories;

• whoami: prints the current user;

• pwd: prints the absolute path to the current directory;

• cat: output the contents of a file;

• Tab: your best friend in the whole world;

Python

Some concepts to remember about Python are:

• There is no need for a main function or for types;

• Indentation is everything

• Basic arithmetic is almost the same as in C/C++;

• ifs, fors, whiles and function declarations all end in a colon (:);

• There's a difference between bytes and strings and they are not interchangeable.
