Answer 1

In Python

if x:

You are alreading checking if x condition is True.

Like Dragos explained x is true.

Continuing

You shouldn't do

if x == True:

In this situation you are asking if x and True have the same reference and off course it doesn't.

Answer 2

x is not an empty list. It contains an empty tuple. So x is True.

Answer 3

Python uses boolean variables to evaluate conditions. The boolean values True and False are returned when an expression is compared or evaluated. 

In this case 1 equals False and 2 equals True

Answer 4

Thanks for the answers. Finally I've got it. I should ask if bool(x) == True and not if x == True.
