Python Tutorial: Mutable variables 2

	# --> METHOD 1: The Pythonic way
	import copy

	list_copy = copy.deepcopy(whoops_list)
	print(list_copy is whoops_list) # Spoiler, it's False

	# --> METHOD 2: The 'I don't have time for this!' guy
	# Don't be this guy

Python tutorial: mutable_vars 1

	# we define a list (mutable type)

	# we equal this list to another variable
	i_am_really_bad_at_python_list = whoops_list

	# we append an item tho the SECOND list

Python Tutorial: Sets

	# Sets are unordered lists of UNIQUE ITEMS, like dictionaries but without
	# values, only keys.
	set_numbers = {5, 3, 6, 7, 7, 7, 7}
	print(set_numbers)

	# they are useful when you need to know which items are in one set and not in the other
	set_numbers_2 = {1, 2, 3, 4, 5}

	# this will print the intersection which is another set = {3, 5}
	print(set_numbers_2.intersection(set_numbers))

Python Tutorial: Dictionaries

	# DISCLAIMER: any coincidence with reality is pure luck, no spoilers ahead
	# having this dictionary of key: GoT character and value: a boolean answering if it's alive or not
	d_got_is_alive = {"John Snow": True, "Tyrion Lannister": True, "Ned Stark": True}

	# to retrieve an item, like lists but by the KEY
	print(d_got_is_alive["Ned Stark"])

	# example with for loop
	# the method .keys() of a dictionary returns a list of the keys in the dictionary. WATXAUT! It might not be ordered!
	for key in d_got_is_alive.keys():

Python Tutorial: Lists

	list_numbers = [12, 33, 44, 55]

	# lists of list are also possible! You can create matrix for example
	jacobean_matrix = [
	[3, 4, 5],
	[1, 0, 4],
	[0, 3, 1]
	]

	# to add things to lists (remember, mutable means mutable like it can change)

Python Tutorial: While loop

	i = 0

	# if you mess with the next line -> boom, infinite loop
	while i < 10:
	print(i)

	# if you don't include this line -> boom, infinite loop
	i = i + 1

Python Training: conditionals

	# here we have one boolean
	some_true_condition = True

	# if the boolean is True, it will print, if not, it won't do anything
	if some_true_condition == True:
	print("Hey this is True")

	if some_true_condition: # This is the same, but more Pythonic
	print("Hey this still is True")

	# ----> Numbers
