Need some python help.

Implement a class Car with the following attributes: make, model (both strings) and year (integer). The class should include implementation of the following methods: A constructor (_init_): the constructor should take three parameters corresponding to the attributes. _str_: this returns a string representation of a car object. _repr_: this would have the same functionality as function str. _It_; this is an implementation of the less-than operator to make it possible to sort Car objects by make. To test the class, you will populate a list of Car objects from an input file containing car entries (make, model, year), one per line (let's call the file cars.txt). After your program reads the cars data into a list, print the list, sort it (using the sort function defined in list), and then print it again
