Python os.path.sameopenfile() Method

  1. Syntax of Python os.path.sameopenfile():
  2. Example Code: Open a Single File Using the os.path.sameopenfile() Method
  3. Example Code: Open Two Different Files Using the os.path.sameopenfile() Method

The sameopenfile() method belongs to the os.path module. The os and the path modules provide procedures to interact with the operating system and file system paths, respectively.

The sameopenfile() method checks if two file descriptors refer to the same resource or not.

Syntax of Python os.path.sameopenfile():

os.path.sameopenfile(fd1, fd2)

Parameters

Type Explanation
fd1 integer A file descriptor associated with a valid resource.
fd2 integer A file descriptor associated with a valid resource.

Return

The sameopenfile() method returns a Boolean value. It returns True if both the file descriptors refer to the same resource; otherwise, it returns False.

Example Code: Open a Single File Using the os.path.sameopenfile() Method

import os
from os.path import sameopenfile

path = "a.txt"
f1 = os.open(path, os.O_RDONLY)
f2 = os.open(path, os.O_RDONLY)
result = sameopenfile(f1, f2)
print(result)
os.close(f1)
os.close(f2)

Output:

False

Since the Python code opened the same file twice concurrently using two file descriptors, the sameopenfile() method returns True.

Example Code: Open Two Different Files Using the os.path.sameopenfile() Method

import os
from os.path import sameopenfile

p1 = "a.txt"
p2 = "b.txt"
f1 = os.open(p1, os.O_RDONLY)
f2 = os.open(p2, os.O_RDONLY)
result = sameopenfile(f1, f2)
print(result)
os.close(f1)
os.close(f2)

Output:

False

Since the Python code is opening two different files, the file descriptors will be different; hence, the sameopenfile() method returns False.
