self parameter

Question

I want to know about self parameter in class in broader way. Can anyone tell me. Why we use self in Python and not in other languages ?

self behaves like this (java) but remember self is not a keyword, you can change self to this also.

class Circle (object):
def __init__(self, radius):
self.radius = radius

circle1 = Circle (10)

change self to this:

class Circle (object):
def __init__(this, radius):
this.radius = radius

circle1 = Circle (10)

in Java:

class Circle {
private int radius;

public Circle (int radius) {
this.radius = radius;
}
}

Circle c = new Circle (10);
