How can I get the size of a file in python?

Problem:

i've done:
        self.logfile = open(filename, 'a')
and i'd like to do this next:
        len_log = self.logfile.size()

...is there something comparable?

Solution:

Indeed there is.  You can do:

        import os
        len_log = os.stat(filename)[6]

This functionality is available on both UNIX and Windows.  To be more
nicely symbolic you could extend the example to:

        import os
        from stat import *
        len_log = os.stat(filename)[ST_SIZE]

which makes it a bit more obvious what's going on.

However, because you are opening self.logfile for appending,
you can use:
        
        self.logfile = open(filename, "a")
        len_log = self.logfile.tell()
