check if list is empty python

>>> if len(a)==0:
    print ("list is empty")
else:
    print ("list is not empty")

if len(li) == 0:
    print('the list is empty')

if not a:
  print("List is empty")

if '' in list:
  # do stuff

For sequences, (strings, lists, tuples), use the fact that empty sequences are false.

Yes: if not seq:
     if seq:

No:  if len(seq):
     if not len(seq):

# An empty list object evaluates to False
a = []
not a
# Output:
# True
