The permissions of a file in a Linux system are split into three sets of three permissions: read, write, and execute for the owner, group, and others. Each of the three values can be expressed as an octal number summing each permission, with 4 corresponding to read, 2 to write, and 1 to execute. Or it can be written with a string using the letters r, w, and x or - when the permission is not granted. For example: 640 is read/write for the owner, read for the group, and no permissions for the others; converted to a string, it would be: "rw-r-----" 755 is read/write/execute for the owner, and read/execute for group and others; converted to a string, it would be: "rwxr-xr-x" Fill in the blanks to make the code convert a permission in octal format into a string format. ?? python code

Answer:

Explanation:

def octal_to_string(octal):

   result = ''

   value_letters = [(4, 'r'), (2, 'w'), (1, 'x')]

   for c in [int(n) for n in str(octal)]:

       for value, letter in value_letters:

           if c >= value:

               result += letter

               c -= value

           else:

               result += '-'

   return result

print(octal_to_string(755))

print(octal_to_string(644))

print(octal_to_string(750))

print(octal_to_string(600))

In this exercise, using the knowledge of computational language in linux, we have that this code will be written as:

The code is in the attached image.

We can write the linux as:

  result = ''

  value_letters = [(4, 'r'), (2, 'w'), (1, 'x')]

  for c in [int(n) for n in str(octal)]:

      for value, letter in value_letters:

          if c >= value:

              result += letter

              c -= value

          else:

              result += '-'

  return result

print(octal_to_string(755))

print(octal_to_string(644))

print(octal_to_string(750))

print(octal_to_string(600))
