Step by step
Solved in 3 steps
- You develop a Python application for your school.You need to read and write data to a text file. If the file does not exist, it must be created. If the file has content, the content must be removed.Which code should you use? Group of answer choices C. open(“local_data”, “w+”) D. open(“local_data”, “w”) A. open(“local_data”, “r”) B. open(“local_data”, “r+”In Python, which of the following opens read_it.txt for writing or reading data text_file variable. a. text_file = open("read_it.txt", "wr") b. text_file = open("read_it.txt", "rw") c. text_file = open("read_it.txt", "aw") d. text_file = open("read_it.txt", "w+") which one is correct?In python, Im not getting an output for this code. import csv tsv_name=input("Enter tsv file name : ")tsv_file=open(tsv_name)read_tsv = csv.reader(tsv_file, delimiter="\t")f=open("report.txt","w")student_cnt=0m1_avrg=0m2_avrg=0fexam_avrg=0for row in read_tsv:student_cnt+=1lname=row[0]fname=row[1]m1=int(row[2])m2=int(row[3])fexam=int(row[4])avrg=(m1+m2+fexam)/3grade=" "if(avrg>=90.0):grade="A"elif(avrg>=80.0):grade="B"elif(avrg>=70.0):grade="C"elif(avrg >=60.0):grade="D"else:grade="F" f.write("%s\t%s\t%d\t%d\t%d\t%s\n"%(lname,fname,m1,m2,fexam,grade)) m1_avrg+=m1m2_avrg+=m2fexam_avrg+=fexam m1_avrg=(m1_avrg/student_cnt)m2_avrg=(m2_avrg/student_cnt)fexam_avrg=(fexam_avrg/student_cnt) f.write("Averages: midterm1 {0:.2f},\tmidterm2 {1:.2f},\tfinal {2:.2f}".format(m1_avrg,m2_avrg,fexam_avrg))f.close()
- In Python, which of the following opens read_it.txt for reading in data text_file varible. a. text_file = open("read_it.txt", "r") b. text_file = open("read_it.txt", "w") c. text_file = open("read_it.txt", "a") d. text_file = open("read_it.txt", "rd") which one is correct?Code should be in Python. A photographer is organizing a photo collection about the national parks in the US and would like to annotate the information about each of the photos into a separate set of files. Write a program that reads the name of a text file containing a list of photo file names. The program then reads the photo file names from the text file, replaces the "_photo.jpg" portion of the file names with "_info.txt", and outputs the modified file names. Assume the unchanged portion of the photo file names contains only letters and numbers, and the text file stores one photo file name per line. If the text file is empty, the program produces no output. (Examples in image)Use python language for a program that modifies and sorts the content of a specific csv file based on the inputted column name. The program should ask Enter filename: Enter column name to be sorted: Additionally, the csv file must be modified and no additional csv files must be created. The application will catch and display an error message "the file does not exist" if the csv file does not exist. *if possibe, do not use pandas*
- 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.The python function get_second_line takes one parameter, fname, the name of a text file. The function should open the file for reading, determine the second line of the file, close the file, and return the second line (a string). NOTE: You may assume the file will have at least two lines.Write a program that asks the user for the name of a file. The program should display only the first five lines of the file’s contents. If the file contains less than five lines, it should display the file’s entire contents.
- 2. File handling is an important part of any application. Assume that, you are asked to build an application to find the harmonic mean in a file. Assume that you have to read the file of "Filel.txt" and print the harmonic mean of each row to an output file "File2.txt". All of the data in the "File1.txt" is comma separated. In file1.txt you are given the name of the data set in first place, then you are given the data list. All of them are comma separated. Your task is to compute the harmonic mean from the given file | for each dataset. The file may contain more than 1000 rows. Write your code by following the requirements. File2.txt harmonic mean of Datal is 3.50 harmonic mean of Data2 is 3.43 harmonic mean of Data3 is 3.50 File1.txt Data1, 3, 4, 4, 3, 3.7, 4, 3.3, 1 Data2, 3, 4, 3.7, 3, 3.7, 4, 3, 1 Data3, 3, 4, 4, 3, 3.7, 4, 3, 2 Data4, 3, 4, 4, 3, 3.7, 4, 3.3, 2 Design a JAVA application that can perform the task with the given scenario. harmonic mean of Data4 is 3.49Using Python A file named data.txt contains an unknown number of lines, each consisting of a single integer. Write a program that creates the following three files: dataplus.txt dataminus.txt zeros.txt The program should read each line of the data.txt file and perform the following: If the line contains a positive number, that number should be written to the dataplus.txt file. If the line contains a negative number, that number should be written to the dataminus.txt file. If the line contains the value 0, do not write the value to a file. Instead, keep a count of the number of times 0 is read from the data.txt file. After all the lines have been read from the data.txt file, the program should write the count of zeros to the zeros.txt file.Write the program FileComparison that compares two files. Two files have been provided for you, Quote.txt and Quote.docx, both containing movie quotes and are located in the /root/sandbox/ directory Note: you will not be able to see the Quote.docx file. Next write the file comparison application that displays the sizes of the two files as well as the ratio of their sizes to each other. To discover a file’s size, you can create a System.IO.FileInfo object using statements such as the following, where FILE_NAME is a string that contains the name of the file, and size has been declared as an integer: FileInfo fileInfo = new FileInfo(FILE_NAME); size = fileInfo.Length; Your program's output should look like the following: The size of the Word file is FILE_SIZE and the size of the Notepad file is FILE_SIZE The Notepad file is x% of the size of the Word file using System; using static System.Console; using System.IO; class FileComparison { static void Main() { // Getting…
