elements pushed into the stack.
ii. Write a function POP() to pop the objects from the stack and displays them. Also,
the function should display “Stack Empty” when there are no elements in the
stack.
For example: If the list contains the following data:
book=[[“Python”, “Arora”,350],[“Hindi”, “ Agarwal”,200] ,
[“English”, “Bernard”,270], [“Physics”, “Arora”,600],
[“Chemistry”, “ Chopra”,550]]
The Output must be:
Count of elements pushed in the stack : 3
[“Chemistry”, “ Chopra”]
[“Physics”, “Arora”]
[“Python”, “Arora”]
Stack Empty
27. Vedika has created a list containing names and marks of 5 students. Write a program,
with separate user-defined functions to perform the following operations:
i) push(lst): To push the name of the students who has scored more than 70

display “Stack Empty” when there are no elements in the stack.
For Example: The list has
lst=[[“Ramesh”,58], [ “Umesh”,78], [ “Vishal”,90], [ “Khushi”,60], [ “Ishika”,95]]
The output must be: Umesh, Vishal , Ishika
28. Write a function in Python, Push(book) where, book is a dictionary containing the
details of a book in form of {bookno : price}.
The function should push the book in the stack which have price greater than 300. Also
display the count of elements pushed into the stack.
For example: If the dictionary contains the following data:
Dbook={"Python":350,"Hindi":200,"English":270,"Physics":600,
“Chemistry”:550}
 The stack should contain
Chemistry
Physics
Python
The output should be:
The count of elements in the stack is 3

29. Write the definition of a user defined function PushNV(N) which accepts a list of
strings in the parameters N and pushes all strings which have no vowels present in it,
into a list named NoVowel.
Write a program in python to input 5 words and push them one by one into a list named
All. The program should then use the function PushNV() to create a stack of words in
the list NoVowel so that it stores only those words which do not have any vowels in it,
from the list All.
Thereafter , pop each word from the list NoVowel and display the message
“EmptyStack”
For example:
If the words accepted and pushed into the list All are
[„DRY‟,‟LIKE‟,‟RHYTHM‟,‟WORK‟,‟GYM‟]
Then the stack NoVowel should store
[„DRY‟,‟RHYTHM‟,‟GYM‟]
And the output should be displayed as
GYM
RHYTHM
DRY
EmptyStack

32. A dictionary stu contains rollno and marks of students. Two empty list stack_roll and
stack_mark will be used as stack. Two functions push_stu() and pop_stu() is defined
and performs the following operation
(a) Push_stu(stu) :- It reads dictionary stu and add keys into stack_roll and values
into stack_marks for all students who secured more than 60 marks.
(b) Pop_stu() :- It removes last rollno and marks from both list and print
"underflow" if there is nothing to remove. For example
stu={1:56,2:45,3:78,4:65,5:35,6:90} values of stack_roll and stack_mark after push_stu()
[3,4,6] and [78,65,90]
