How can you determine an empty set of elements in Python?

In Python, you can determine if a collection is empty in several ways, depending on the type of collection:
- For lists, tuples, sets, and dictionaries, you can simply check their boolean value:
my_list = []
if not my_list:
print('List is empty')
- To check if a string is empty, similarly:
my_str = ''
if not my_str:
print('String is empty')
- If you have an iterator or generator, you can try to get the first element using
next()and handle theStopIterationexception.
Thus, the most universal way is to use the check if not collection: — empty collections in Python are considered False in a boolean context.
