Julie has created a dictionary containing names and marks as key value pairs of 6 students. Write a program, with separate user defined functions to perform the following operations:
-
Push the keys (name of the student) of the dictionary into a stack, where the corresponding value (marks) is greater than 75.
Pop and display the content of the stack.
For example: If the sample content of the dictionary is as follows:
R={"OM":76, "JAI":45, "BOB":89, "ALI":65, "ANU":90, "TOM":82}
The output from the program should be: TOM ANU BOB OM
Answer
Program:
myDict = {"OM":76, "JAI":45, "BOB":89, "ALI":65, "ANU":90, "TOM":82} #creating a dictionary
def func_push(stack, name):
stack.append(name) #it appends the received name(key) to the stack
def func_pop(stack):
if stack != []:
return stack.pop() #return the topmost name if stack is not empty
else:
return None
myStack = []
for i in myDict: #with each iteration,i represents each key(name) of myDict dictionary(key value pairs)
if myDict[i] >= 75: #myDict[i] represents values of myDict dictionary(key value pairs)
func_push(myStack, i) #if value of key value pair is >=75,then name(key) is pushed in stack
while True:
if myStack != []: #check if the stack is empty or not
print(func_pop(myStack), end = " ") #if not empty, then pop out content of stack
else:
break
Output:
TOM ANU BOB OM
