Program Listing

my_dict = {'A': 40, 'B': 60, 'C': 100,

'D': 20, 'E': 90, 'F': 80}

k = Counter(my_dict)

# Finding 3 highest values

high = k.most_common(3)

print()

print("\tFINDING THREE HIGHEST VALUES IN A DICTIONARY")

print()

print("\tInitial Dictionary:")

print()

print("\t",my_dict, "\n")

print("\tDictionary with 3 highest values:")

print("\tKeys: Values")

print()

for i in high:

print("\t",i[0],":", i[1],"")

print()

print("\tEND OF PROGRAM”)

CREATING A NESTED DICTIONARY IN PYTHON

Write a program to create nested dictionary and display the result on the screen.

display_dictionary = {1: 'Fundamentals', 2: 'of', 3: 'Python Programming',

4: {'A': 'Welcome', 'B': 'To', 'C': 'Bacolod City'}}

print()

print("\tCREATING A NESTED DICTIONARY")

print()

print("\tDISPLAY RESULT")

print()

print("\t",display_dictionary);

print()

print("\tEND OF PROGRAM").

COMBINE THREE DICTIONARY ADDING VALUES FOR COMMON KEYS IN PYTHON

Write a program to combine two dictionary-adding values for common keys and display the result on the screen.

from collections import Counter

a1 = {'a': 10, 'b': 20, 'c':30}

a2 = {'a': 20, 'b': 10, 'c':40}

a3 = {'a': 30, 'b': 40, 'c':20}

display_result = Counter(a1) + Counter(a2) + Counter(a3)

print()

print("\tCOMBINE THREE DICTIONARY ADDING VALUES FOR COMMON KEYS")

print()

print("\tDISPLAY RESULT")

print()

print("\t",display_result)

print()

print("\tEND OF PROGRAM")

ITERATE OVER DICTIONARIES USING FOR LOOPS IN PYTHON

Write a program to iterate over dictionaries using for loops and display the result on the screen.

display = {'a': 5,'b':10,'c':15,'d':20,'e':25}

print()

print("\tITERATE OVER DICTIONARIES USING FOR LOOPS")

print()

print("\tDISPLAY RESULT")

print()

for dict_key, dict_value in display.items():

print("\t",dict_key,'->',dict_value)

print()

print("\tEND OF PROGRAM")

ADD NEW ITEM IN THE DICTIONARY IN PYTHON

Write a program to add an item in the dictionary and display the result on the screen.

add_item = {

"brand": "Hyundai",

"model": "Accent",

"year": 2012

}

add_item["color"] = "red"

print()

print("\tADD NEW ITEM IN THE DICTIONARY")

print()

print("\tDISPLAY RESULT")

print()

print(" ",add_item)

print()

print("\tEND OF PROGRAM");

CHECK IF A GIVEN KEY ALREADY EXISTS IN A DICTIONARY IN PYTHON

Write a program to check if a given key already exists in a dictionary and display the result on the screen.

list = {1:5,2:10,3:15,4:20,5:25,6:30,7:35,8:40}

def check_key(a):

if a in list:

print('\tThe key {0} is present in the dictionary.'.format(a))

else:

print('\tThe key {0} is not present in the dictionary.'.format(a))

print()

print("\tCHECK IF A GIVEN KEY ALREADY EXISTS IN A DICTIONARY")

print()

print("\tDISPLAY RESULT")

print()

check_key(7);

print()

print("\tEND OF PROGRAM");

SUM OF ALL THE ITEMS IN THE DICTIONARY IN PYTHON

Write a program, take a dictionary, and print the sum of all the items in the dictionary and display the result on the screen.

print()

print("\tSUM OF ALL THE ITEMS IN THE DICTIONARY")

print()

display={'a':10,'b':20,'c':30,'d':40,'e':50}

print("\tDISPLAY RESULT")

print()

print("\tThe total sum is" ,sum(display.values()),".")

print()

print("\tEND OF PROGRAM”)
