为什么 self 没有定义并给我不同的结果？

Question

this code should do

• kilometer to meter convert
• meter to kilometer convert
• float should work
• should use classes and input
• doesn't matter you input km or m it will convert each other to each other
• sorry to my english

class Convertor:    
    def __repr__(self, kilometer,meter):
        self.kilometer = metri/1000 
        self.meter = kilometri*1000

    def __str__(self):
        return self.kilometer, self.meter


program=input("please input number in KM or M: ")
if program=="KM" or "km":
    kilometri=input("please input only km: ")
if kilometri==int or float:
    print(self.kilometer)
else:
    print('please input only digits')

Answer 1

If you want to call a self variable outside of Class, try like this:

variable = ClassName()
variable.kilometri
