Word IndexWrite a python program that reads the contents of a text file. The program should create a dictionary inwhich the key-value pairs are described as follows:Key. The keys are the individual words found in the file.576Values. Each value is a list that contains the line numbers in the file where the word (thekey) is found.For example, suppose the word “robot” is found in lines 7, 18, 94, and 138. The dictionarywould contain an element in which the key was the string “robot”, and the value was a listcontaining the numbers 7, 18, 94, and 138.Once the dictionary is built, the program should create another text file, known as a word index,listing the contents of the dictionary. The word index file should contain an alphabetical listingof the words that are stored as keys in the dictionary, along with the line numbers where thewords appear in the original file. Figure 9-1 shows an example of an original text file(Kennedy.txt) and its index file (index.txt
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
Find Country Function Name: findCountry() Parameters: capitalList ( list ) Returns: Dictionary mapping each capital to its country( dict ) Description: Given a list of countries' capital cities, write a function that returns a dictionary that maps a capital to its country's name. Note: Assume that all capital cities provided are valid. example test cases: >>> findCountry(('tokyo', 'delhi', 'stockholm']) {'tokyo': 'Japan', 'delhi": 'India', 'stockholm': 'Sweden'} >>> findCountry(l'paris', 'canberra', 'copenhagen']) {'paris': 'France', 'canberra': 'Australia', 'copenhagen': 'Denmark'} For this assignment, use the REST countries API (https://restcountries.com/#api-endpoints-v2). For all of your requests, make sure you to use version 2 of the REST countries API (V2), not version 3 (V3.1). If you make a request with the URL: https://restcountries.com/v2/alpha/usa, you will receive the following response: { "name": "United States of America", "topLevelDomain": [".us"], "alpha2Code": "US",…
Extract increasing integers from digit string def extract_increasing(digits): Given a string of digits guaranteed to only contain ordinary integer digit characters 0 to 9, create and return the list of increasing integers acquired from reading these digits in order from left to right. The first integer in the result list is made up from the first digit of the string. After that, each element is an integer that consists of as many following consecutive digits as are needed to make that integer strictly larger than the previous integer. The leftover digits at the end of the digit string that do not form a sufficiently large integer are ignored.This problem can be solved with one for-loop through the digits that looks at each digit exactly once regardless of the position of that digit in the beginning, end or middle of the string. Keep track of the current number (initially zero) and the previous number to beat (initially minus one). Each digit d then updates current = 10*current+d to…

python exercise: Write a Python function called get_top_students that takes the list of dictionaries as input and returns a dictionary containing the name and GPA of the top two students in the list. Each dictionary has the following keys: "name", "age", "major", and "gpa".
3. form_letter This function takes a list of dictionaries, where each dictionary has an entry of key "name" and entry of key "date". It returns a list of strings, where each output string has replaced the name and the date into the following template. Use the format method on strings -- see Lecture 8! The template should be exactly like this -- just copy-paste this into your code. TEMPLATE = """Dear {name},Your appointment is at {time}.Thanks very much.-- bimmy""" It can be either local to your function, or global in your Python file. Your choice! Sample calls should look like this. >>> form_letter([{"name":"Alex", "time":"three o'clock"},{"name":"Laura", "time":"the stroke of midnight"}])["Dear Alex,\nYour appointment is at three o'clock.\nThanks very much.\n-- bimmy", 'Dear Laura,\nYour appointment is at the stroke of midnight.\nThanks very much.\n-- bimmy']
▾ Part 4: Order Up! Complete the function order lunches, which takes two arguments: • stock: A dictionary that contains menu items available for purchase at a restaurant. The dictionary maps each item's name to an integer that represents how many of each item is available (e.g., 'soda': 4). orders: A list of strings representing items that patrons at the restaurant have ordered. The list might include items not available for purchase. The function iterates over the orders list, treating each string in the list as a key in the stock dictionary. If the key is present in the dictionary, the function decrements the value associated with the key (provided that doing so would not make the value negative). The function also returns the total number of valid items purchased (as an integer). The function simply ignores strings in orders that are not valid keys in stock. As an example, suppose stock were the dictionary {soda': 0, 'burger: 3, 'chips': 5, pizza': 7} and orders were [soda',…
Capital Quiz use pythonThe Capital Quiz ProblemWrite a program that creates a dictionary containing the U.S. states as keys, and their capitals asvalues. (Use the Internet to get a list of the states and their capitals.) The program should thenrandomly quiz the user by displaying the name of a state and asking the user to enter that state’s574capital. The program should keep a count of the number of correct and incorrect responses. (Asan alternative to the U.S. states, the program can use the names of countries and their capitals
Python Dictionary Help: Part a) Read a text file and then convert the elements into a dictionary. For example, you have the following in your names.txt: John, Likeable, Charming, Studious Mary, Beautiful, Relaxed, Studious, Strong Convert it to dict = {0: {'Name':'John', 'Attributes':'Likeable, Charming, Studious'}, 1: {'Name':'Mary', 'Attributes':'Beautiful, Relaxed, Studious, Strong'},} Part b) Convert the following list: [{'Name': 'John', 'Attributes': ['rude, 'bad', 'lazy']}, {'Name': 'Mary', 'Attributes': ['loud', 'disruptive']}] Into a dictionary like the one above.
