True/False 9. A Python dictionary is a kind of sequence.
Dictionary & Tuple
1. Write a Python program to combine two dictionaries into one by adding values for
common keys. Input contains two comma separated dictionaries. Print the new
dictionary and create a tuple which contains unique values in sorted order.
Sample Input
а: 100, b: 100, с: 200, d: 300
а: 300, b: 200, d: 400, e: 200
Sample Output
{'a': 400, 'b': 300, 'c': 200,'d': 700, 'e': 200}
Values: (200, 300, 400, 700)
6.
2. 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

Sample Output
10 - 2 times

30 - 1 times
50 - 1 times
90 - 1 times

Python coding language
Create a static dictionary with a number of users and with the following values:
First name
Last name
Email address
Password
Ask the user for:
5. Email address 6. Password
Loop (for()) through the dictionary and if (if()) the user is found print the following:
7. Hello, first name last name you have successfully logged in 8. Notify the user if the password and email address are wrong 9. Additional challenge: if you want the program to keep asking for a username and password when the combination is wrong, you will need a while() loop. 10. Save the file as assignment03yourlastname.py
