Hi! Today, I learned to make my own classes. I did run into a few problems whilst working on today's project but luckly I managed to figure it out.

# Creating Class
class User:
    # Creating Attribute
    def __init__(self, user_id, username):
        self.user_id = user_id
        self.username = username
        self.followers = 0
        self.following = 0

    # Creating Method
    def follow_count(self):
        self.followers += 1
        print(f"Yay! You have {self.followers} followers.")

    def follow(self, user):
        self.following +=  1
        user.followers += 1

        print(f"Yay! You are following {self.following} user(s).")
        print(f"Yay! They now have {user.followers} follower(s).")

user_1 = User("001", "Palak")
print(user_1)
user_2 = User("002", "Hirave")
print(user_2)
print(user_1, user_2)

user_3 = User("003", "Damn")
# Adding another attribute
user_3.notes = "~Yay~"
print(user_3.notes)

# Having a default value (followers are 0) to use later
user_4 = User("004", "Kevin")
print(user_4.followers)
user_4.followers += 1
print(user_4.followers)
print(user_4.follow_count())

print(user_1.follow_count())
print(user_3.follow_count())

user_4.follow(user_1)
user_4.follow(user_1)
user_4.follow(user_1)
user_4.follow(user_1)
