a simple calculator

[Solstice]

I think i finally understand how to make it work.
does this code look good to you?

class calculator:
    def __intit__(self):
        self.num1=None
        self.num2=None
        self.num3=None
        self.mode="none"

    def banner(self):
        print("░▒▓██████████████████▓▒░")
        print("░Calculator by solstice░")# bug in the site, not my fault
        print("░▒▓██████████████████▓▒░")

    def choose_mode(self):
        self.mode=input("+,-,*,/?")

    def get_numbers(self):
        self.num1=input("input number one")
        self.num2=input("input number two")

    def calculate(self):
        if self.mode == "+":
            self.num3=int(self.num1)+int(self.num2)

        if self.mode == "-":
            self.num3=int(self.num1)-int(self.num2)

        if self.mode == "*":
            self.num3=int(self.num1)*int(self.num2)

        if self.mode == "/":
            self.num3=int(self.num1)/int(self.num2)

        print(self.num3)

def main():
    c = calculator()
    c.__init__()
    c.banner()
    c.choose_mode()
    c.get_numbers()
    c.calculate()

while True:
    main()
