Python os.pathconf() Method with example



Hello dear readers! Welcome back to another section of my tutorial on Python. In this tutorial guide, we are going to be studying about the Os pathconf() method.

The Python os pathconf() method returns the system configuration information relevant to a named file.

Syntax

Below is the syntax for Python Os pathconf() method -

os.pathconf(path,   name);


Parameter Details

  • path - This is the file path.
  • name - This specifies the config value to retrieve; it may be a string, which is the name of a defined system value; these names are been specified in a number of standards (POSIX.1, Unix 95, Unix 98).

Return Value

This returns system configuration information of a file.

Example

The following below is a simple example -

#!/usr/bin/python

import os, sys

print "%s" % os.pathconf_names

# Retrieve maximum length of a filename
no = os.pathconf('a2.py', 'PC_NAME_MAX')
print "Maximum length of a filename :%d" % no

# Retrieve file size
no = os.pathconf('a2.py', 'PC_FILESIZEBITS') 
print "file size in bits  :%d" % no

Output
When the above code is executed, it will produce the following result -

{'PC_MAX_INPUT': 2, 'PC_VDISABLE': 8, 'PC_SYNC_IO': 9, 
'PC_SOCK_MAXBUF': 12, 'PC_NAME_MAX': 3, 'PC_MAX_CANON': 1, 
'PC_PRIO_IO': 11, 'PC_CHOWN_RESTRICTED': 6, 'PC_ASYNC_IO': 10, 
'PC_NO_TRUNC': 7, 'PC_FILESIZEBITS': 13, 'PC_LINK_MAX': 0, 
'PC_PIPE_BUF': 5, 'PC_PATH_MAX': 4}
 Maximum length of a filename :255
 file size in bits : 64


Alright guys! This is where we are rounding up for this tutorial post. In my next tutorial, we are going to be discussing about the Python OS pipe() Method.
