Use Dictionary and tupples to solve the problems in PYTHON. Thank You <3

Write a python program which prints the frequency of the numbers that were given as input by the user. Stop taking input when you find the string “STOP”. Do not print the frequency of numbers that were not given as input. Use a dictionary to solve the problem

3. Write python code to invert a dictionary. It should print a dictionary where the keys are values from the input dictionary and the values are lists of keys from the input dictionary having the same value. Make sure the program handles multiple same values. 

 

Sample Input 

key1 : value1, key2 : value2, key3 : value1 

 

 

Sample Output 

{ “value1” : [“key1”, “key3”], “value2” : [“key2”] } 

 

 

 

 

Two words are anagrams if they contain all of the same letters, but in a different order. For example, “evil” and “live” are anagrams because each contains one “e”, one “i”, one “l”, and one “v”. 

Write a program that reads two strings from the user and determines whether or not they are anagrams. Use a dictionary to solve the problem. 

 

Sample Input 

Sample Output 

evil 

Those strings are anagrams. 

live 

On some basic cell phones, text messages can be sent using the numeric keypad. 

Because each key has multiple letters associated with it, multiple key presses are needed for most letters. Pressing the number once generates the first character listed for that key. Pressing the number 2, 3, 4 or 5 times generates the second, third, fourth or fifth character.

Write a program that displays the key presses needed for a message entered by the user. 

Construct a dictionary that maps from each letter or symbol to the key presses needed to generate it. Then use the dictionary to create and display the presses needed for the user’s message.
