People also ask, Can you create an empty set in Python?

In **Python**, we must use the set() method without any **parameters to produce** an empty set; if we use **empty curly braces** ” “, we will obtain an **empty dictionary**. If you print “type(x)” after writing the previous code (construct an empty set in **Python**), the result will appear as a “class’set’> “.
