Getting file size in Python?

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.

@Selena, You can use os.path.getsize(path) which returns the size of the path in bytes.It also raises an OSError in case, the file does not exist or is inaccessible.

import os

path = 'C:\\Python27\\Lib\\genericpath.py'

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

print(stat_info)

Output:

243 

You can also use os.stat(path) method to give the status of the path specified:

Ex-

import os

path = 'C:\\Python27\\Lib\\genericpath.py'

Stat_info = os.stat(path)

print(stat_info)

 

Output:

os.stat_result(st_mode=34188, st_ino=725981, st_dev=2867, st_nlink=1, st_uid=1000,st_gid=1000, st_size=243, st_atime=15315670940, st_mtime=1630306690, st_ctime=15303487690)
