- Write a function in python named "read_words" that declares a parameter for a filename and returns a collection of unique words in the file. Even though words.txt contains a single word per line, you should not assume that this is true of every file. For example, if the line is a sentence, you should split the line into individual words before storing each word in your collection. Handle any errors that occur by printing a detailed error message. Hint: the Python set works like Java's HashSet.I need help converting the following pseudocode into a working Raptor flowchart // The two senior class homerooms at Littleville High School// are having a fundraising drive for the prom. Each time a student// solicits a contribution, a record is created with the// student's name and the value. Two files have been created for// Homeroom A and Homeroom B. Each file is sorted in contribution// value order from highest to lowest. This program merges the two files.start Declarations string roomAName num roomAValue string roomBName num roomBValue string bothFilesDone = "N" num HIGH_VALUE = 999999 InputFile roomAFile InputFile roomBFile InputFile mergedFile getReady() while bothFilesDone = "N" detailLoop() endwhile allDone()stop getReady() open roomAFile "roomAFile.dat" open roomBFile "roomBFile.dat" open mergedFile "mergedFile.dat" readA() readB() checkBoth()return readA() input roomAName, roomAValue from roomAFile…W rite a function named sum_ints that takes no parameters and returns an integer. The function will read a file named "low.txt". Each line of this file will be a properly written whole number. Your function should return the sum of all of those numbers. f = open("low.txt") (PYTHON) No hand written and fast answer with explanation
- Write a C program that, given a text file, constructs Huffman code based on the character frequencies of the file and then encodes the file accordingly. The executable must accept the following command line options:• -i filename for the input file • -o filename for the output file Use the fread function, use FILE, size, etc. Please use the following to write the code: #include <stdio.h> #include <stdlib.h> #include <string.h> #include <getopt.h>In Python, Create a program that will write 100 integers created randomly in a file. The integers will be separated by a space in the file. Read the data back from the file, and display the sorted data. The program should prompt the user to enter a file name. Utilize the following function headers for this problem: Main() WriteNumbers(filename) ReadNumbers(filename) The main function will first prompt the user to enter the filename. Then the main function calls WriteNumbers-then ReadNumbers. The WriteNumbers function opens an output file and writes 100 random numbers as long a large string text. Do not use lists for this problem- please just write a random number followed by a space 100 times. The ReadNumbers function will then read the text file and display the numbers sorted. In order to sort the numbers, read the big string and then split it into a list. Now convert them into integers by using list comprehension and then sort the list. Loop through the list and print each…Modify this program so that it writes the values in two columns, like this: 32.00 54.00 67.50 29.00 35.00 80.00 115.00 44.50 100.00 65.00 Total: 622.00 Complete the following file: total.cpp 1 #include #include 3 #include #include 5 using namespace std; 4 7 int main() 8 { // Prompt for the input and output file names cout » input_file; cout > output_file; 10 11 12 13 14 // Construct the streams for reading and writing ifstream in(input_file); ofstream out(output_file); 15 16 17 18 // Check for errors and format the output stream if (in.fail() || out.fail(O) { return - 1; } out > value) { out <« setw(15) <« value <« endl; total = total + value; } 26 27 28 29 30 31 32 33 out << setw(8) << total « endl; 34 35 return 0; 36 }
- Assume the file list contains the names of several of the files listed in your home directory. What is the result of running the following? $ wc `cat list`can you make the code down below handle division by zero exception and print the following error: ZeroDivisionError float division by zero print("Please enter the file name :") name = input() # to check whether entered file exists or not try: file = open(name, 'r')#open file in read mode lines = file.readlines()# read data in list of strings in 'lines' list numbers = [] for num in lines: numbers.append(num.strip().split())# change each string in list 'lines' to a list and append to new declarednumber list file.close() # close the file for n in numbers:#numbers becomes a list of list #try block to handle Type error that is flow value must convert into float type try: n[2] = round(float(n[2]),4) #convert n[2] to a float as n[2] contains flow value n.append("{0:.3f}".format(n[2]/3.6)) #append the converted flow value in liter/sec into each list n #try block to handle division by zero error try: sub = round((n[2]-50.285), 4) n.append("{0:.3f}".format(n[2]/sub))#calculate f/(f-50.285)…In Python Write a program that consists of (at least) two function: A function that creates and saves data in a file. The saved data represents exam grades. In the function, you will create n random numbers in the range [0,100], where n is the number of students. The function can be called as follows: createFile(filename, n) Main function, in which the user inputs the file name and the number of students, then the main calls function createFile. The main should perform validation for n (should be > 0), and the filename (should end with .txt). I will explain how to validate strings in the coming lecture. Hint: a good developer will write four functions to solve the problem.
- Include the code to any h files usedWrite two c++ programs to implement a distributed version of a multithreaded Huffman decompressor using the one in project 1 The server program The user will execute this program using the following syntax: ./exec_filename port_no < input_filename where exec_filename is the name of your executable file, port_no is the port number to create the socket, and input_filename is the name of the file with the alphabet's information. The port number will be available to the server program as a command-line argument. The server program receives from STDIN the alphabet's information (using input redirection). The input file has multiple lines, where each line contains information (character and frequency) about a symbol from the alphabet. The input file format is as follows: A char representing the symbol. An integer representing the frequency of the symbol. Example Input File: E 3 G 3 F 1 H 2 Given the previous input file, the expected output for the…Assume the file data.dat contains a sequence of binary data. Write a program that creates another file named reverse.dat that is a reverse copy of data.dat . For example, the first byte of reverse.dat should be the same as the last byte of data.dat . The second byte of reverse.dat should be the same as the next-to-last byte of data.dat . And so on. Handle exceptions in the following manner: If a FileNotFoundException is thrown, the program should display the string " File Error ". If any other exception is thrown, the program should display the string " Error ". The program should not display any screen output unless an exception is thrown as described above. The name of your program class must be ReverseFile .4 Suppose we have the following code in a file named a_b_c.h: #define TRUE 1 #define A_B_C int main(void) { } and the following code in a file named a_b_c.c: 10 #if TRUE #include #include "a_b_c.h" printf("A Big Cheery \"hello\"!\n"); return 0; A_B_C #endif er 5th b When we try to compile the program, the compiler complains. Why? Can you inter- bas change two lines in one of the files so that the program compiles and runs? Explain.
