To know if a list is empty, we only need to know if list count equal 0; thus, we should not provide a function that checks if a list is empty. code example
Example 1: how to tell if a list is empty in python
if not a:
print("List is empty")
Example 2: can python tell if a list is empty
>>> if len(a)==0:
print ("list is empty")
else:
print ("list is not empty")
