Python: Get the size of a file

Python Basic: Exercise-87 with Solution

Write a Python program to get the size of a file.

Sample Solution-1:

Python Code:

import os
file_size = os.path.getsize("abc.txt")
print("\nThe size of abc.txt is :",file_size,"Bytes")
print()

Sample Output: 

The size of abc.txt is : 0 Bytes

Sample Solution-2:

Python Code:

import os
file_size = os.stat('main.py')
print("\nThe size of abc.txt is :",file_size.st_size,"Bytes")

Sample Output: 

The size of abc.txt is : 104 Bytes

Sample Solution-3:

Python Code:

import os
file = open('main.py')
file.seek(0, os.SEEK_END)
print("The size of main.py is :", file.tell(), "bytes")

Sample Output: 

The size of main.py is : 117 bytes

Python: Tips of the Day

Find current directory and file's directory:

To get the full path to the directory a Python file is contained in, write this in that file:

import os 
dir_path = os.path.dirname(os.path.realpath(__file__))

(Note that the incantation above won't work if you've already used os.chdir() to change your current working directory, since the value of the __file__ constant is relative to the current working directory and is not changed by an os.chdir() call.)

To get the current working directory use

import os
cwd = os.getcwd()

Documentation references for the modules, constants and functions used above:

  • The os and os.path modules.
  • The __file__ constant
  • os.path.realpath(path) (returns "the canonical path of the specified filename, eliminating any symbolic links encountered in the path")
  • os.path.dirname(path) (returns "the directory name of pathname path")
  • os.getcwd() (returns "a string representing the current working directory")
  • os.chdir(path) ("change the current working directory to path")
