Example 1: how to check if value is in list python

>>> letters = [a,b,c,d,e]
>>> 'a' in letters:

Example 2: python checking not in list

a = [1, 2, 3, 4, 5, 6]
b = 7
c = 4

# use "not in" to check if something is not an element of a list
# use "in" to check if something is an element of a list

  print('True')
else:
  print('False')

if c in a:
