Name binding in function statements

Question

The following Python program:

d = {}

for x in range(3):
    d[x] = lambda: x

print(d[0](), d[1](), d[2]())

outputs:

2 2 2

x is bound by reference in the lambda expression. After the for statement, x is bound to 2, which explains the output.

I would like x to be bound by value instead, to get the following output:

0 1 2

How can I achieve this?
