I understand that python provides a value for self when methods are called on the instance of a class.
However, I don't understand how self works when assigning value to a variable of instance.

class snake:
    def __init__(self,name):
        self.name=name#this is the bit I don't understand. How is self.name #interpreted by python?

Look over this code sample, it should be very explanatory:

# role of self in Python classes
# self can be named different, but 'self' is convention

class Snake:
    def __init__(self, name):
        # self keeps track of each instance
        # and also makes self.name global to class methods
        self.name = name
        # test

    def isnice(self):
        # a class method has self as the first argument
        return self.name + " is very nice"

# create 2 instances of class Snake
bob = Snake('Bob Python')
mary = Snake('Mary Rattle')


# now you can get the name that has been assigned to self.name

# access the class method

"""my result -->
# self for each instance has a different location in memory
