- The python function file_first_chars takes one parameter, fname, the name of a text file, and returns a string made up of the first character from each line in the file. You may assume there are no blank lines in the file. Hint: Use a for loop to iterate over the lines of the file and accumulate the string of first characters.## This function is used to generate the input file Directory.txt# def generateInputFile():try:lines=['Springsteen, Bruce, 2587.\n','Hassan, Amir, 6958.\n','Homes, Rebecca, 5263\n','Smith, John, 5252\n','MacDonald, Mirna, 8965!\n','Pichai, Sundar, 9632.\n','Jobs, Steve, 1002\n','Goldsmith, Micheal, 5478.\n','Yassir, Ammar, 8885\n','Nicholas, Jack, 4696\n','Pang, Chee, 9898\n','Lee, Andrew, 7412.\n','Jimenez, Dragos, 6547\n'] outfile = open("Directory.txt",'w')for line in lines:outfile.write(line) except Exception as ex:print(ex)finally:outfile.close()generateInputFile() use this code to get the file and please match the answer with the sample runConsider the following code segment: done = False while not done : try : filename = input("Enter the file name: ") inFile = open (filename, "r") except IOError : print ("Error: File not found.") It is supposed to keep on prompting the user for file names until the user provides the name of a file that can be opened successfully. What line of code should be placed in the blank to achieve this goal? Select one: done = inFile done = True done = not inFile done = False
- The function print_last_line in python takes one parameter, fname, the name of a text file. The function should open the file for reading, read the lines of the file until it reaches the end, print out the last line in the file, report the number of lines contained in the file, and close the file. Hint: Use a for loop to iterate over the lines and accumulate the count. For example: Test Result print_last_line("wordlist1.txt") maudlin The file has 5 lines.Write a python code that reads a file (contents of the file pasted below) and shows the average of all values shown in the last column. File Name: data.txt File Contents (of data.txt): Admin 100 300 tmp 20 Admin 100 300 tmp 30 Admin 100 300 tmp 20 Admin 100 300 tmp 10 Admin 100 300 tmp 60 Admin 100 300 tmp 95 Admin 100 300 tmp 100 Admin 100 300 tmp 24 Admin 100 300 tmp 99 Admin 100 300 tmp 50Using C++Put your entire completed visual studio solution in a zip archive and upload it as: assignment01YourName.zip. Write the program that allows the user to sort using the Bubble Sort, Selection Sort, Insertion Sort and Shell Short The program should be able to read in data from a binary file. The first element of the binary file will be used to tell how many elements to read in. Once all the data has been read in, the program should sort the data. The user should be able to choose which algorithm to use to sort the data. The program should print the time before and after the sort. The last part of the program should prompt the user for a lower and upper bound. These two value should then be used to decide how much and which part of the array will be display. You should test all of the sorts on each of the data files. In a separate word document include a short writeup for each sort that looks something like this: Insertion Sort: 1,000,000 Random: 5 minutes 1,000,000…
- Answer the given question with a proper explanation and step-by-step solution. 1- Write code that does the following: opens an output file with the filename number_list.txt, uses a loop to write the numbers 1 through 100 to the file, then closes the file.Write a regular expression that matches filenames that contain a(n) Slovakia personal numberThis function is used to create a bank dictionary. The given argument is the filename to load. Every line in the file should be in the following format: key: value The key is a user's name and the value is an amount to update the user's bank account with. The value should be a number, however, it is possible that there is no value or that the value is an invalid number. What you will do: - Create an empty bank dictionary. - Read in the file. - Add keys and values to the dictionary from the contents of the file. - If the key doesn't exist in the dictionary, create a new key:value pair. - If the key does exist in the dictionary, increment its value with the amount. - You should also handle the following cases: -- When the value is missing or invalid. If so, ignore that line and don't update the dictionary. -- When the line is completely blank. Again, ignore that line and don't update the dictionary. -- When there is whitespace at the…
- *Code in Python Write a script named dif.py. This script should prompt the user for the names of two text files and compare the contents of the two files to see if they are the same. If they are, the script should simply output "Yes". If they are not, the script should output "No", followed by the first lines of each file that differ from each other. The input loop should read and compare lines from each file, including whitespace and punctuation. The loop should break as soon as a pair of different lines is found. Below are examples of the program input and output along with relevant files: one.txt: This is text. abc 123 sameAsOne.txt: This is text. abc 123 differentFromOne.txt This is text. xyz 123 Comparing files that are the same: Enter the first file name: one.txt Enter the second file name: sameAsOne.txt Yes Comparing files that are different: Enter the first file name: one.txt Enter the second file name: differentFromOne.txt No abc xyzyou will need to create the following textbook specified files.
