Question

what is the use of membership operator and list the membership operator with an example​

Answer 1

Answer:

Membership operators are operators used to validate the membership of a value. It tests for membership in a sequence, such as strings, lists, or tuples.  

 in operator: The ‘in’ operator is used to check if a value exists in a sequence or not. Evaluates to true if it finds a variable in the specified sequence and false otherwise.

Explanation:

# Python program to illustrate

# Finding common member in list

# using 'in' operator

list1=[1,2,3,4,5]

list2=[6,7,8,9]

for item in list1:

   if item in list2:

       print("overlapping")      

else:

   print("not overlapping")

The same example without using in operator:

# Python program to illustrate

# Finding common member in list

# without  using 'in' operator

 

#  Define a function() that takes two lists

def overlapping(list1,list2):

 

   c=0

   d=0

   for i in list1:

       c+=1

   for i in list2:

       d+=1

   for i in range(0,c):

       for j in range(0,d):

           if(list1[i]==list2[j]):

               return 1

    return 0

list1=[1,2,3,4,5]

list2=[6,7,8,9]

if(overlapping(list1,list2)):

   print("overlapping")

else:

   print("not overlapping")
