Note the types of objects in the dictionary! It is a reverse operation compared to lab 10.13. 1. Create a function load_dict_from_csv(filename) that will accept the string with the file name and returns the loaded storage. 1.0, Use with to open the file with the required filename. 1.1. Crete a future dictionary. Create csv loader to load all lines 1.2. Loop over loader to get each line from the file. Using knowledge about the structure of the dictionary to parse the line (convert it to required types if needed!) and save it to the dictionary. The first element is a key, the other is the values: second is the name, third is the prct, and the rest is the grades_list. 2. You do not have to have any if name _main__" statement, but you can use it and IDE on your computer to test your == program. Examples of function work: storage_save.txt 101,quiz,12,1,2,3,4 102,final,53,10,10,10,10 103,labs,30,100,100,100,97,100,96,100,98,97,100 res = load_dict_from_csv ("storage_save.txt") res >>> { 101: ["quiz", 12, [1,2,3,4]], 102: ["final", 53, [10, 10, 10, 10]], 103: ["labs", 30, [100,100,100,97,100,96,100,98,97,100]] }

Overview This program will have you cut and past a dictionary called food_dict from the specifications, the programmatically go through the list to find people who have not yet listed their favorite foods. It will then ask for their foods, update the dictionary, and finally print it at the end. Note: I will change the dictionary during grading Expected Output Example 1 What is Janelle's favorite food? Steak What is Thomas's favorite food? What is Yolanda's favorite food? Soup Here are the favorite foods: Jim's favorite food is Tacos Bob's favorite food is Burgers Janelle's favorite food is Steak Lisa's favorite food is Pizza Thomas's favorite food is Pho Yolanda's favorite food is Soup Finn's favorite food is Bread Specifications • You should submit a single file called M4A5.py • It should follow the submission standards outlined here: Submission Standards • Your program must loop through the dictionary to find empty values. • You must copy this dictionary definition to the top of your…
IN PYTHON how did read from a file and make a dictionary, assigning the data from the file i imported as keys and values of the dictionary I'm making.
Estimated Completion Time: 2 minutes You are now working for Prof. Midas on a research project. You are given this piece of code to review which is intended to be a better and faster implementation of a function that checks whether a given key is in a dictionary (i.e., key lookup). You have to present your findings to Prof. Midas. Select all the findings which you will NOT present (i.e., select all answers which are FALSE). def key_in_dict(d, k): for item in d: if k == item: return True return False This code would always be slower than the builtin key lookup Python provides. O A key lookup in a dictionary in Python is generally faster than determining whether a value is in a list. O This code is way faster and will be included in the next version of Python (version 4.1). The code is incorrect from a functional perspective, the True and False should be switched. This code could be replaced with one line: return k in d O The code is correct and would always perform faster than the…

Using Python, write a program which opens a text file and loads the data into a dictionary where the key is the line # from the file and the value is the line of text from the file. For instance, if the file looks like: Hello,Welcome to Introduction to Big Data It is good to meet everyone.Hope you enjoy the class. The dictionary should look like: KEY VALUE 1 Hello, 2 Welcome to Introduction to Big Data 3 It is good to meet everyone. 4 Hope you enjoy the class. Then change it to a list and reverse the order of the lines of text and save it back to a new text file.

Topic: Database On my bookshelf of paper books, I have a dictionary that consists of multiple volumes, each of which is a book. One covers A-E, another F-J, another K-M, and so on. To find a word, I look at the alphabetic ranges to find the right volume. Then I use the ranges at the top of each page to turn to the proper page. Then I find the word on the page. Pick the correct answer. A. Multi-level Indexes B. Secondary indexes C. None the above
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
PYTHON QUESTION This assignment requires you to create a dictionary by reading the text file created for the Chapter 6 assignment. The dictionary should have player names for the keys. The value for each key must be a two-element list holding the player's goals and assists, respectively. See page 472! Start with an empty dictionary. Then, use a loop to cycle through the text file and add key-value pairs to the dictionary. Close the text file and process the dictionary to print the stats and determine the top scorer as before. In fact, much of the code used in program6_2.py can be copied and used for this program. Printing the stats for each player is the most challenging part of this program. To master this, refer to the examples in the zip file that can be downloaded from the "Dictionary values can be lists" link in the "Learn Here" part of this module. NOTE: you do not need to submit the text file. Submit just this program. The required output should be the same well-formatted table…

PYTHON PROGRAMMING. USE PROVIDED STARTING CODE TO COMPLETE THIS TASK. Create a glossary (dictionary) of technical terms and definitions. It will be set up as a Python dictionary structure. The file glossary_starter.py is a complete starter framework for the assignment. It includes some initial values for the dictionary. It is long because most of the code has already been written for you. Your task is to complete the five individual functions for adding and deleting terms, looking up terms, listing them, and printing out both the terms and definitions. These functions are all short, just a couple of lines, and use basic dictionary methods and techniques.
