Can you explain this output?

Question

x=([])
print(bool(x)) #output=False,but why...
y=[()]
print(bool(y)) #output=Ture,but why....
can anyone explain this.

Answer 1

The first, x, is an empty list. The second list, y, is not empty.

print(bool(([],))
will return true as it is a tuple containing an empty list.

Answer 2

Good question!

[()] is not empty because it is a list containing a tuple.

But, ([]) becomes just [] because python thinks there are just extra parentheses. However, if you try putting a comma after the list like so:

([],) or just [],

Suddenly it becomes a tuple containing an empty list.

Hope this helped :)
