Original answer: https://stackoverflow.com/a/2104107/5283213

Use os.stat, and use the st_size member of the resulting object:

import os
statinfo = os.stat('somefile.txt')

print statinfo
(33188, 422511L, 769L, 1, 1032, 100, 926L, 1105022698,1105022732, 1105022732)

print statinfo.st_size
926L

Output is in bytes.

edit to check if 10MB file or not

It's simple: use an if statement and some maths:

if statinfo.st_size <= 10485760: # and not 10 000 000 as 1024 * 1024 * 10
    print "size is less than 10MB"
else:
    print "greater than 10MB"

@SunehaBanuJ if it *did* work, then mark the answer as accepted for others to review later :) – Sreetam Das Jun 01 '17 at 10:18
It *was* pointed out before, and I flagged the question too, but the OP's question needed more, et al, the `if` statement. – Sreetam Das Jun 01 '17 at 10:52

You could use this

import os
os.path.getsize('path_to_dir/file.txt')

or

os.stat('path_to_dir/file.txt').st_size

Meanwhile, this is a duplicate question. Next time onwards do make sure to check if a question on the same already exists. Cheers!
