- What can you determine about a file by looking at it's properties ?Structural in-dependence exists when it is possible to make changes in the file structure without affecting the application program's ability to access the data. Select one: True FalseWhat distinguishes a file's logical description from its physical description?
- Objective: 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:…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…As data is read from the file, the read position moves forward, closer to the end.
