Answer 1

Abhishek Mazumder , normally variables do need to be declared or initialized. But in your case you are using somethin like this:

x*=n-(r-(r-i))

so this means the same as: x = x * n-(r-(r-i)). this will assign the right side expression to x. When x is not declared, this creates an error, because x is also in the expression on the right side.

Answer 2

Means that you reffer to the x variable before it is assigned

In your case it is never assigned

Answer 3

Abhishek Mazumder variables in python are assighned just by giving them a value.

Answer 6

Abhishek Mazumder,
x=x*(n-(r-(r-i)
Can only be done if x already has a value
While asigning a variable you cant use its own name in its value

Answer 7

Should add an variable x=1
And then
X=n-(r(r-i))
