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

not x

if x is false, then True, else False

# We have an empty dictionary x
x = {}

# Check if dictionary x is empty
if not x:
print("Dictionary is empty")
Dictionary is empty

As dictionary x is empty, not x is True and "Dictionary is empty" is printed.
