Booleans in this code

Hi, could someone please help me understand why all the True and False in this code? Thanks in advance

Code:

omelet_ingredients = {"egg":2, "mushroom":5, "pepper":1, "cheese":1, "milk":1}
fridge_contents = {"egg":10, "mushroom":10, "pepper":3, "cheese":2, "tomato":4, "milk":15}
have_ingredients =[False]
if fridge_contents["egg"] > omelet_ingredients["egg"]:
    have_ingredients[0] = True
    have_ingredients.append("egg")

if fridge_contents["mushroom"] > omelet_ingredients["mushroom"]:
    if have_ingredients[0] == False:
        have_ingredients[0] = True
    have_ingredients.append("mushroom")

if fridge_contents["pepper"] > omelet_ingredients["pepper"]:
    if have_ingredients[0] == True:
        have_ingredients[0] = False
    have_ingredients.append("pepper")

if fridge_contents["cheese"] > omelet_ingredients["cheese"]:
    if have_ingredients[0] == False:
        have_ingredients[0] = True
    have_ingredients.append("cheese")

if fridge_contents["milk"] > omelet_ingredients["milk"]:
    if have_ingredients[0] == True:
        have_ingredients[0] = False
    have_ingredients.append("milk")

if have_ingredients[0] == False:
    print("I have the ingredients to make an omelet!")

Ignore the TRUE and FALSE use in this example, as it is logically flawed and will only confuse you, see it as the example on IF statements in IF statements it is.
