Because there is no nested scope for the x variable.So your list looks
like this: [lambda :x, lambda :x, lambda :x, lambda :x, lambda :x,
lambda :x, lambda :x, lambda :x, lambda :x, lambda :x] with x having the
value 9, being the last value through the loop. So your code is
quivallent to the following. >>> li=[lambda :x for t in range(10)]
>>> x = 9

What you probably want is the following:

>>> li = [(lambda t: lambda :t)(x) for x in range(10)]
