1. Write a program that displays a rank in the defined dictionary. Save it as searchRank.py. a) create a dictionary, rank = {1:"Freshman", 2:"Sophmore", 3:"Junior", 4:"Senior" } b) request a user input for a number of years. c) print the value of the matching key in the dictionary. d) print the error message if input is invalid. Output Example 1: Enter the # of years in the school (1-4): 1 Year 1 = Freshman

Capital QuizWrite a program that creates a dictionary containing the U.S. states as keys, and their capitals as values. (Use the Internet to get a list of the states and their capitals.) The programshould then randomly quiz the user by displaying the name of a state and asking the userto enter that state’s capital. The program should keep a count of the number of correct andincorrect responses. (As an alternative to the U.S. states, the program can use the names ofcountries and their capitals.) in phyton

Overview This program will have you use a loop to prompt a user for three games and their systems and then store them in a dictionary called games_dict). Then it will ask the user for the worst game, delete that game, and print out the contents of the revised games_dict. Expected Output Example 1 What is a great game? Mario What system can I play that on? Nintendo What is a great game? Sonic I play that on? Sega What system can What is a great game? Spyro What system can I play that on? layStation That's too many, let's get rid of one What game should we remove? Sonic The new dictionary is: You can play Mario on Nintendo You can play Spyro on PlayStation Specifications • You should submit a single file called M4A3.py • It should follow the submission standards outlined here: Submission Standards • Your program should start by defining an empty dictionary called games_dict • It should populate games_dict using a for-loop • It should print out games_dict using a for-loop.

Python Programming Assignment: Create a dictionary that takes a basketball team's information (that includes team's name and points) as parameter, creates a teams_dict and returns it. Also, create a parameter for write_file parameter that opens current results text file in write mode and writes the dictionary information to file as per format and closes the file.
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
Code the following directions in python. 1.Assume the variable dct references a dictionary. Write an if statement that determines whether the key 'Jim' exists in the dictionary. If so, delete 'Jim' and its associated value. 2.Write code to create a set with the following integers as members: 10, 20, 30, and 40. 3.Assume each of the variables set1 and set2 references a set. Write code that creates another set containing all the elements of set1 and set2, and assigns the resulting set to the variable set3.

8. Name and Email Addresses Write a program that keeps names and email addresses in a dictionary as key-value pairs. The program should display a menu that lets the user look up a person’s email address, add a new name and email address, change an existing email address, and delete an existing name and email address. The program should pickle the dictionary and save it to a file when the user exits the program. Each time the program starts, it should retrieve the dictionary from the file and unpickle it.
Overview This is a review assignment where you will use multiple tools you have picked up so far throughout the course. If you're confused about how to do something make sure you look back at earlier assignments. In this program you will start by declaring an empty dictionary named population_dict. Then you will use a while-loop to prompt a user for a series of cities and their populations, storing the input in population_dict). After this you will prompt the user to decide what is the maximum population for a city to be considers a small down. Finally, you will open a file called populationdata.txt where you will write the results. Expected Output Example of standard out (the console): What is next city? (enter q to quit) Long Beach What is the population of Long Beach? 362000 What is next city? (enter q to quit) Los Angeles What is the population of Los Angeles? 382000000 What is next city? (enter q to quit) San Diego What is the population of San Diego? 136000000 What is next city?…

File Encryption and DecryptionWrite a program that uses a dictionary to assign “codes” to each letter of the alphabet. Forexample:codes = { ‘A’ : ‘%’, ‘a’ : ‘9’, ‘B’ : ‘@’, ‘b’ : ‘#’, etc . . .}Using this example, the letter A would be assigned the symbol %, the letter a would beassigned the number 9, the letter B would be assigned the symbol @, and so forth.The program should open a specified text file, read its contents, then use the dictionaryto write an encrypted version of the file’s contents to a second file. Each character in thesecond file should contain the code for the corresponding character in the first file.Write a second program that opens an encrypted file and displays its decrypted contentson the screen. in phyton
