- Storing data in a file can help the permanent storage of data. While trying to enter data in multiple lines program terminates on \n°. Explain with the help of a code how will you read and write the data in a file in multiple lines.Word List File WriterWrite a program that asks the user how many words they would like to write to a file, andthen asks the user to enter that many words, one at a time. The words should be writtento a file. (in phyton)PYTHON without def function Problem Statement Assume an input file (called "numbers.txt") contains a number on each non-blank line of the file. Read in the file and then print out the sum of all the numbers read. The sum should be rounded up to 1 decimal. Sample Input (File numbers.txt) 1.0 2.0 3.25 4.0 Sample Output 10.3
- File Attributes 5. File attributes (a) File name: file name is a very important file attribute When a file changes name, it seems to change its identity (just like when you change your name) The oldest file naming we may remember is the 8 +3 convention in DOS (in DOS, all file names can NOT be bigger than 8 characters, special characters like spaces were not allowed etc.). So a file like C:\\Program Files\\Adobe\\Photoshop can cause problems in DOS, and it has to be represented in different ways using strange character like~ (tilde). Elaborate on your understanding of file names or file naming in different operating systems (Windows, Mac, Linux etc.). For example, some OS like NTFS may allow longer file name, allow space, and even allow non English like characters such as Chinese file names. Is there a maximum length of file names (can you have a file name of 1,000 characters long?) (b) File creation date and modification date. File can be created and modified using different ways of…File Handling in Python 1. Create a python program that will search string/strings (can use operator such as s* - all that starts with s, sdf etc..) in a txt file and returns something such as # of times the string/strings appears 2. A python program that will search file from a directory or entire drive note: ask user input for directory pathObjective: Practice file handling Lab Description: Write a python script (with comments) that computes the average score for an unknown number of students in a file. Specifically, your script should: Ask for a filename name (that has scores in it) Open the scores file Verify the scores file opened correctly Read the student's name and their four scores Display the student's name, all of their scores and their average to the screen Writes the students name and the scores' average to a file name "averages.csv" Close both files For example, the following are examples of correct execution (with the text in bold being the input from the user): Input file project4-inputA.txt: Output to the screen: Output file "averages.csv" Мary 76 89 82 100 Joey Please enter the scores filename: project4-inputA.txt # Student name, grade average You entered project4-inputA.txt Opened scores file project4-inputA.txt Mary scores: 76.0 89.0 82.0 100.0 average: 86.75 Joey scores: 91.0 81.0 83.0 95.0 average:…
