- The function file_first_chars in python 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. NOTE: Return the function, don't print For example: Test Result print(file_first_chars("wordlist1.txt")) hsaempls code in pythonplagiarism: This Boolean function takes two filenames. If any line occurs in both files, return True.If not, return False. I suggest using nested loops. With nested loops, we call the loop that is in thebody of the other loop, the "inner loop". The loop that contains the inner loop is the "outer loop". Openthe second file inside the outer loop:for line1 in file1:file2 = open(fname2)for line2 in file2:Python only lets you read the file once per open, so you need this order of instructions. Make sure yourreturn False is outside of both loops. Otherwise, you will only compare the first two lines of thefiles. Make sure you close the file that gets read repeatedly after the inner loop but still inside the outerloop.Here is some (more complete) pseudocode to get you started:open file 1for line1 in file 1open file 2for line2 in file 2:if line1 == line2:return Trueclose file 2return Falsenum.txt is a file that contains a list of scores. num.txt 10 25 36 45 89 42 54 create a program that reads the scores from num.txt file one line at a time. The program should display their total and average. since the number of scores is unknown, the program must keep looping until readline is blank. Sample Output: There are 7 scores The total is 301 T he average is 43.0
- Please fill in the ellipsis(...) of how to read and write the levels(values) from a file for a price_checker: #Method : Load levelsList using the data in levelsFiledef readLevelsFromFile(self):try:# Set levelsList to an empty listself.levelsList = []# Open the file...# Use a loop to read through the file line by line...# If the last two characters in the line is "\n", remove them......# Append the line to levelsList...# Close the file...except:return #Method: Write levelsList to levelsFile (override the existing file)def writeLevelsToFile(self):# Open the file in a way that will override the existing file (if it already exists)...# Use a loop to iterate over levelsList item by item...# Convert everything in the item to and then add \n to it - before writing to the file... # Close the file... # *************************************************************************************************# Main Code Section#…A program stores the prime numbersin a file named PrimeNumbers.dat. Write a program that finds the numberof prime numbers that are less than or equal to 12, 120, 1,200, 12,000,100,000, 1,200,000, 12,000,000, 120,000,000, 1,200,000,000, and12,000,000,000. Your program should read the data from PrimeNumbers.dat.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.
- The python function first_words takes one parameter, fname, the name of a text file, and returns a list containing the first word from each line of the file. For example, if the file contents are: apples are red bananas are yellow limes are green then the list ["apples", "bananas", "limes"] should be returned.NOTE: You may assume the file will contain no blank lines.BIG HINT: If line is a string representing a line of text (inside of a for loop!), then L = line.split() creates a list of the words in the line.The program takes a single argument as the name of the file to be read. A sample file is named (Movies.txt). The program reads this file which has labeled columns separated by commas. Every row of this text file includes information about a movie. You are asked to read every row as a string and decompose the given information (separated by commas). If a costumer wants too see "List of the Genres" (or genre,score,year) all genres type must be show. I need this answer in C language. Please explain nicely. Thanks.You will need the two files attached to this note: GirlNames.txt and BoyNames.txt.GirlNames.txt file contains a list of the 200 most popular names given to girls born in the UnitedStates from the year 2000 through 2009. BoysNames.txt does the same for boys.Write a program that reads the contents of the two files into two separate lists. The user should be ableto enter a boy’s name, a girl’s name, or both, and the application will display messages indicatingwhether the names were among the most popular.Hint: there might be list functions that do a fast search versus using an IF statement.
- What type of loop, such as counter control or sentinel control, will you use in each of the following situations?a. Sum the following series: 1 + (2 / 1) + (3 / 2) + (4 / 3) + (5 / 4) + ... + (10 / 9)b. Sum the following numbers, except the last number: 17, 32, 62, 48, 58, -1c. A file contains employees’ salary. Update employees’ salary.PYTHON!!!! Write a program that allows the user to navigate the lines of text in a file. The program should prompt the user for a filename and input the lines of text into a list. The program then enters a loop in which it prints the number of lines in the file and prompts the user for a line number. Actual line numbers range from 1 to the number of lines in the file. If the input is 0, the program quits. Otherwise, the program prints the line associated with that number. An example file and the program input and output is shown below: example.txt Line 1. Line 2. Line 3. Enter the input file name: example.txt The file has 3 lines. Enter a line number [0 to quit]: 2 2 : Line 2. The file has 3 lines. Enter a line number [0 to quit]: 4 ERROR: line number must be less than 3. The file has 3 lines.
