'list()' invokes the list class, which creates and returns a new list.
Since you haven't passed any arguments, the list is empty.
'list' refers to the list class itself.
Here is a more in-depth example, using functions instead of classes:
def hello(name):
return 'Hello'.
If you call this function, like so:
greeting = hello()
print greeting
You will get the output 'Hello'.
But, if you just REFER to the function, instead of actually CALLING it:
greeting = hello
print greeting
You will get this output:
<function hello at 0xbb266bc4>
Because you omitted the double parentheses, you're getting the hello
function object itself, instead of the RESULT of that function.
