Complete the below function that takes a file name and a list as arguments and reads the text within the corresponding file, then creates a dictionary whose keys are the characters of the provided list, and the values are the counts of these characters within the text. If a character in the list is not included in the text, "0" should be written in the dictionary as the value of this character. The function returns the created dictionary as a result. If the file does not exist, then the function returns an empty dictionary. Here is an example case, assuming a file named "sample.txt" exists with the following content: ----- sample.txt ----- This is an example sentence. This is yet another sentence. » text2dict("sample.txt", ['a', 'b', 'c', 't']) {'a':3, 'b':0, 'c':2, 't':4} def text2dict(filename, characters): return # Remove this line to answer this question

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.
There are 5 big names of a certain field: Tom, Jerry, Snoopy, Pooh and Luffy, whose ID are 88888, 5555555, 11111, 12341234 and 1212121, respectively. Please organize those data in dictionary. Program to achieve the following function: After a user inputs the name of a big name, it outputs his/her ID. Separate the results for two blanks with a semicolon. 1- def find person(dict_users, stru): (stru): 1f dict users. return dict_users[stru] else: return 'Not Found' 3 6 name _nain_": dict_users = {'Tom' : 88888, "Jerry':5555555, 'Snoopy':11111, 'Pooh":12341234 Luffy':12i2121) stru = Input ('Please input the name: ') orintiltind person( dict users. 7- if Input/Output : 1 >>> Please input the name: Jerry 5555555 >>>
Your program should prompt the user to enter names and salaries from the user. Create a dictionary called information which should be initialized by the values from the two lists that you created above. Your program should pass this dictionary to a function named insights which would calculate and print the names and salaries for each employee. Before printing the salary, your function should multiply the salary by a random number and then print it. [26] For example, name = Employee01, salary = 100 new_salary = salary * random number between 1 and 10
Word FrequencyWrite a python program that reads the contents of a text file. The program should create a dictio-nary inwhich the keys are the individual words found in the file and the values are the number of timeseach word appears. For example, if the word “the” appears 128 times, the dictionary wouldcontain an element with 'the' as the key and 128 as the value. The program should eitherdisplay the frequency of each word or create a second file containing a list of each word and itsfrequency.
Problem Statement: The program takes a string and creates a dictionary with key as first character and value as the count of letter in the string and also, sort the dictionary w.r.t the values of count in descending order or sort it based on the key in alphabetical order. Pseudocode: Start of build_dict function An empty dictionary is declared Start of for loop to traverse through the letters of the string If letter is not present as a key in the dictionary The letter is initialized as the key and assign 1 to it ( since initially the count would be 1) Else The value of the letter as key in the dictionary is increased by 1 End of build_dict function Sort the dictionary and assign it back to the same dictionary variable Start of print_dict function Iterate over all the items of the dictionary Print the key and value End of print_dict function Start of main function User must enter a large string and store it in a variable Call the build_dict function with string parameter and return the…
JS Write a function named number_of_pairs whose parameter is an object/dictionary with strings as keys and integers as values. Your function should returns the number of key-value pairs in the parameter.
Exercise: Check Monster Character Exists Description In this series of exercises, you will create functionsto create, modify and examine dictionaries thatrepresent characters in an animated film, and thecast members who voice the characters. Thekeys of the dictionary will be character names.The values in the dictionary will be voice actornames. For this exercise, you will create a function thatchecks if a character is already in the dictionary. Files • monsterfunctions.py : set of functions to work with monster cast dictionaries. Function Name has_character Parameters • monsters: a dictionary • character: a string, the name of a character Action Checks if character is a key in monsters. Return Value True if character is a key in monsters, otherwise False. Examples monsters = create_monster_cast()monsters = add_cast_member(monsters, "Mike", "William Crystal")has_character(monsters, "Mike") -> Truehas_character(monsters, "Sully") -> False
Write a function called count_duplicates that takes a dictionary as an argument and returns the number of values that appear two or more times.
Write a function called dict_intersect that takes two dictionaries as argumentsand returns a dictionary that contains only the key/value pairs found inboth of the original dictionaries.
Task 01 Write a function that takes a dictionary as a parameter. The dictionary holds student names as keys and their mid-term marks in the python course as values. Your function should get the student name corresponding to the minimum and maximum mark achieved by the student and return it to the function call. Then, finally prints the returned statement after the function call. Sample Input: {'Samin': 25, 'Lily': 28,'Akib': 17,'Salma': 22, 'Imon': 20 } Function Call: function_name({'Samin': 25, 'Lily': 28,'Akib': 17,'Salma': 22, 'Imon': 20 }) Sample Output: Highest scorer: Lily Lowest scorer: Akib Sample Input: {"A":60,"B":30,"P":2, "R":8, "S":33, "T":88} Function Call: function_name({"A":60,"B":30,"P":2, "R":8, "S":33, "T":88}) Sample Output: Highest scorer: T Lowest scorer: P
File Analysis USING PYTHON- DICTIONARY NOTE FIND ATTACHED BELOW 2 FILES THA SHOULD BE USED FOR THIS ASSIGNMENT Using python, Write a program that reads the contents of two text files and compares them in the followingways:It should display a list of all the unique words contained in both files.It should display a list of the words that appear in both files.It should display a list of the words that appear in the first file but not the second.It should display a list of the words that appear in the second file but not the first.It should display a list of the words that appear in either the first or second file, but notboth.Hint: Use set operations to perform these analyses. ATTACHED FILES first FILENAME: first_file.txt The quick brown fox jumps over the lazy dog. Second FILENAME: second_file.txt Jack be nimble, Jack be quick, Jack jump over the candlestick. . For the program, you need to write: Comments for all the values, constants, and functions IPO Variables Pseudocode
