- A task in this lab is a dictionary object that is guaranteed to have key-value pairs that follow certain constraints: Every task must have a "name" key, with the value being a string of the task's name Every task must have a "description" field, with the value being a string of the task's description Every task must have a "priority" field, with the value being a number 1-5, representing the task's priority 1 stands for "Lowest" (priority) 2 stands for "Low" (priority) 3 stands for "Medium" (priority) 4 stands for "High" (priority) 5 stands for "Highest" (priority) Every task must have a "deadline" field, with the value being a task's deadline represented as a valid date-string in slashed-format (ex. "02/05/2022") Note: we are using the US format for strings: <MM>/<DD>/<YEAR>. 01/02/2022 represents January 2nd, 2022. Every task must have a "completed" field, with the value being a Boolean value representing whether a task is completed or not Here is an…Create a database with several built-in functions.1) Which method in the interface for a dictionary collection returns an iterator on the keys in the dictionary? a. values() b. pairs() c. keys() d. entries() 2) Which method in the interface for a dictionary collection returns an iterator on the values in the dictionary? a. entries() b. values() c. keys() d. pairs()
- In Python, write a code with describtion that shows how you would add new address entries into a database table, in an addressbook database that contains the fields for first name, last name, address, and phone number. The table should have no duplicates.Implement a blog server in C 1. Implement get of all posts (GET /posts), and individual post (GET /post/1) 2. Implement creation of post (POST /posts). Allow the user to enter their name, but check that they are a valid user in db. Do error checking! The user should not specify the post id; that should come from the database. 3. Write three html files to test this; serve them with the blog server: index.html shows the list of posts with a link to each. post.html shows a post. publish.html allows the creation of a new post. Link these together as a user would expect!Design a class that acquires the JSON string from question #1 and converts it to a class data member dictionary. Your class produces data sorted by key or value but not both. Provide searching by key capabilities to your class. Provide string functionality to convert the dictionary back into a JSON string. question #1: import requestsfrom bs4 import BeautifulSoupimport json class WebScraping: def __init__(self,url): self.url = url self.response = requests.get(self.url) self.soup = BeautifulSoup(self.response.text, 'html.parser') def extract_data(self): data = [] lines = self.response.text.splitlines()[57:] # Skip the first 57 lines for line in lines: if line.startswith('#'): # Skip comment lines continue values = line.split() row = { 'year': int(values[0]), 'month': int(values[1]), 'decimal_date': float(values[2]),…
- Write a program that will allow a user to enter students into a database. The student information should include full name, student ID, GPA and status. The program should allow delete any student based on student ID. Program must use linked list. No vectors or arrays. C++.Please answer the ques in python with showing the answers. Q: A car dictionary: a) Implement a dictionary car with the keys brand, model, and color. Give appropriate values for each key (you choose). b) Print each item in the dictionary (see example output) c) Add a key transmission to the dictionary with the value ‘automatic’. d) Print the value for the key transmission (use the get method). Output Example: subaru crosstrek sapphire blue automaticWrite Java code for a class named MetaDisplay that implements a static void printTable(String r) method. This function performs "select * from r" and generates a table with attribute names. Please provide JDBC procedures for data retrieval. T?
- Regarding a dictionary, which of the following is not true? This is for python. A dictionary can contain another dictionary. A dictionary contains key-value pairs, typically separated by a colon. A dictionary can be modified. The contents of a dictionary can be accessed by using either its keys or by using indexing.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.Answer the following based on the photo: What is the name of ADT? What is the data type of the queue? What is the variable that will store the capacity of the queue? How many pointer variables are there? How many operations are there in the class? In what operation will the size of the array be defined?
