A class is a block of code that holds various functions. Because they
are located inside a class they are named methods but mean the samne
thing. In addition variables that are stored inside a class are named
attributes. The point of a class is to call the class later allowing you
to access as many functions or (methods) as you would like with the same
class name. These methods are grouped together under one class name due
to them working in association with eachother in some way.třídy v pythonu

def __init__(self, name, colour, taste):
self.name = name
self.colour = colour
self.taste = taste

fruit1 = Fruits(apple, red, sweet)
print(fruit1.name)
#this will print the name which is apple

#this will print the colour which is red
