Answer»

def push(stack):

s=[]

print “STACK BEFORE PUSH” display(stack)

s.append(input(“Enter student rollno?”))

s.append(raw_input(“Enter student name”))

s.append(raw_input(“Enter student grade”))

stack, append(s)

def display (stack):

l=len(stack)

print “STACK CONTENTS”

for i in range(l-1,-1,-1):

print stack[i]

stack=[]

print “Creating Stack”

n = input(“Enter the number of students”)

for i in range(n): student = []

student.append(input(“Enter student rollno?”))

student.append(raw_input(“Enter student name”))

student.append(raw_input(“Enter student grade”))

stack, append(student) push(stack)

display(stack)
