27. Problem to check whether a list contains a sublist or not.

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 :

				
					Sublist exists

by

In this program, we will take a user input as a string and convert it into a list. To check for words that have vowels in string with the help of the below-given steps.

Words which has vowels in string:

Steps to solve the program
  1. Take a string as input.
  2. Split the given string using split() and create an empty list.
  3. Using for loop and if statement check whether a word in the splitter string contains any vowels.
  4. If it has any vowels then add that word to the empty list.
  5. Print the list to see the words which has vowels in string.
				
					#Input string
string = "www Student ppp are qqqq learning Python vvv"

#Splitting a atring
string2 = string.split()

#Creating an empty list
list1 = []

for words in string2:
    for char in words:
    #Checking for vowels
        if char == "a" or char == "e" or char == "i"
        or char == "o" or char == "u":
            list1.append(words)
            break
            
#Printing output 
print(list1)

Output :

				
					['Student', 'are', 'learning', 'Python']
