In Python any object can be tested for truth value (true or false).
Empty sequences and collections such as '', (), [], {}, set(), range(0) are considered false.
We can combine this with the boolean operation not x:
Operation | Return value |
|---|---|
| If |
Examples
Empty string
To check whether x is an empty string:
x = ''not x
True
As x is an empty string that has truth value false, not x returns True.
Not empty string
To check whether y is an empty string:
y = 'abc'not y
False
As y is not an empty string, it has truth value true hence not y returns False.
