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 boolean operation:
Operation | Result |
|---|---|
| if |
# We have an empty dictionary xx = {}
# Check if dictionary x is emptyif not x: print("Dictionary is empty")
Dictionary is empty
As dictionary x is empty, not x is True and "Dictionary is empty" is printed.
