N.B.
🐍 Remember the general rules of sorting: numbers are sorted in either ascending or descending order (according to the attribute specified); strings are sorted in alphabetical order, latin letters first, then cyrillic; first uppercase, then lowercase. Numbers in form of a string are sorted according to their codes (e.g. 11 comes after 2 when being sorted in ascending order, but “11” comes before “2”, while sorting as string type)
🐍 Be careful when referring to the keys in the dictionary. Square brackets in the dictionary call a specific element that is already in the dictionary, not an element by its index. For example, if we want to access the first element in a = {1:”one”, 2:”two”} by typing a[0], KeyError will occur: we tried to access a “0” key in a dictionary that doesn’t contain it

🐍 * and ** in the function definition are the unpacking operators
🐍 *args (Non-Keyword Arguments) allows you take in more arguments than the number of formal arguments that you previously defined (e.g. a multiply function that takes any number of arguments and is able to multiply them all together)
🐍 **kwargs (Keyword Arguments) is used to pass a keyworded argument list where you provide a name to the variable as you pass it into the function, the same way a dictionary maps each keyword to the value that we pass alongside it
🐍 It is possible to use the functions you created in the code text of another function’s definition
