  1. Take two lists as input.
  2. Print the elements from the list1 who are not in list2.
  3. Use for loop and an if statement for this purpose.
				
					#Input list
list1 = [34,55,12,89,44,67]
list2 = [55,89,34]

for value in list1:
    if value not in list2:
    #Printing output
        print(value, end=" ")

Output :

				
					12 44 67

28. Problem to generate all sublists with 5 or more elements.

by

In this program, we will take a user input as a list. Generate all sublists having 5 or more elements in it from the given list with the help of the below-given steps.

Generate all sublists of a list:

Steps to solve the program
  1. Take a list as input and create an empty list to store and generate all sublists.
  2. From itertools import combinations for generating sublists with 5 or more elements.
  3. Use for loop and range function for this purpose.
  4. If the generated list contains 5 or more elements add that list as a sublist to the empty list.
  5. Print the list to see the output.
				
					#Importing combinations
from itertools import combinations

#Input list
list1 = [1,3,5,8,0,22,45]

#Creating an empty list
sub = []

for i in range(0,len(list1)+1):
#Checking for combinations
    for sublist in combinations(list1,i):
        temp = list(sublist)
        if len(temp) > 4:
            sub.append(temp)

#Printing output
print(sub)

Output :

				
					[[1, 3, 5, 8, 0],

by

In this program, we will take two lists as inputs and check whether the list contains a sublist with the help of the below-given steps.

List contains a sublist:

Steps to solve the program
  1. Take two lists as input.
  2. Check whether list2 is a sublist of list1 (i.e. all the elements from the list2 are in list1.
  3. Use for loop for this purpose.
  4. Print the output.
				
					#Input list
list1 = [22,45,67,12,78]

#Sublist
list2 = [45,12]

#Creating count variable
count = 0

for value in list1:
    for element in list2:
        if value == element:
            count += 1
            
#Printing output
if count == len(list2):
    print("Sublist exists")
else:
    print("Sublist does not exists")

Output :
