Write a file which gives the same output as while typing mount command in the terminal.
1. #!/usr/bin/env python
2. f = open("/proc/mounts")#opens file /proc/mounts
3. s = f.readlines()# reads the file line by line
4. for x in s[1:]:# for loop which ignores the first line of the file and begins from the second line of the file
5. b = x.split(" ")#splits the file line by line according to spaces
6. del b[-2]#deletes the second last zero from the file
7. del b[-1]#deletes the last zero from the file
8. b.insert(2,"type ")# the string "type" is inserted in index 2
9. b.insert(1,"on")# the string "on" is inserted in index 1
10. b.insert(5,"(")# the opening bracket "(" is inserted in the 5th index
11. b.insert(7,")")# the closing bracket ")" is inserted in the 7th index
12. str = " ".join(b)# the splitted string is joined using the join() functi on
13. print str #the required output is printed; for loop ends
14. f.close()# file is closed
For the required problem, the python code along with sufficient comments is given above. The file /proc/mounts is opened using the open() function and is read line by line using the readlines() function. Then using a for loop the required changes are made so that the output of this program matches exactly with the output of the mount command in the terminal. The necessary insertions and deletions whatever done is mentioned alongside the code in form of comments.
The actual link of the code is given in, ` mount.py <https://github.com/PrithaGanguly/Home_Tasks/blob/master/mount/mount.py/>`_.
