Getting file size in Python? [duplicate]

Question

Is there a built-in function for getting the size of a file object in bytes? I see some people do something like this:

def getSize(fileobject):     fileobject.seek(0,2) # move the cursor to the end of the file     size = fileobject.tell()     return size  file = open('myfile.bin', 'rb') print getSize(file) 

But from my experience with Python, it has a lot of helper functions so I'm guessing maybe there is one built-in.

Use os.path.getsize(path) which will

Return the size, in bytes, of path. Raise OSError if the file does not exist or is inaccessible.

import os os.path.getsize('C:\\Python27\\Lib\\genericpath.py') 

Or use os.stat(path).st_size

import os os.stat('C:\\Python27\\Lib\\genericpath.py').st_size  

Or use Path(path).stat().st_size (Python 3.4+)

from pathlib import Path Path('C:\\Python27\\Lib\\genericpath.py').stat().st_size
