Python - Test Boolean Value of Dictionary

To test the boolean value of a dictionary in Python, you can simply use the dictionary in a context that expects a boolean, such as an if statement. An empty dictionary evaluates to False, while a non-empty dictionary evaluates to True.

Here's a demonstration:

dict1 = {} dict2 = {'key': 'value'} # Testing dict1 if dict1: print("dict1 is True") else: print("dict1 is False") # This will be printed # Testing dict2 if dict2: print("dict2 is True") # This will be printed else: print("dict2 is False") 

This behavior is consistent with other Python built-in data structures. For example, an empty list, tuple, or string all evaluate to False, whereas non-empty ones evaluate to True.
