size of a file or a pcikled object

[shussai2]

Hi,

I want to calculate the size of a file or a pickled object. So say if a file is 2Kb (displayed in Windows file explorer) then I want the same information be displayed in python too.

reasonfile = open('test.csv', 'r')
#----I don't know the command to calculate size of a file--
print "File size is ", filesize

PLUS

Is there any way I can calculate the size of a pickled object.

>>> pickleddictionary = cPickle.dumps(dictionary)
>>> pickleddictionary
"(dp1\nS'w'\nS'1'\ns."
#---Don't know the code to calculate size--------

For the first part use the stat() call. Here's the manual page for it:

As for the second, try: len( pickleddictionary ), that will give you the number of characters in your string.
