reading from a gzip file

P: n/a
Hello,

I have a gzip file and I try to read from this file withe the next
statements:

gunziped_file = gzip.GzipFile('gzip-file')
input_file = open(gunziped_file,'r')

But I get the nezt error message:

Traceback (most recent call last):
File "read_sfloc_files.py", line 131, in ?
input_file = open(gunziped_file,'r')
TypeError: coercing to Unicode: need string or buffer, instance found

I think that I do some mistake. Would some body tell me what is my
mistake?

You're opening the gzip file and then passing the gzip file object as
a filename to open(). The documentation for the gzip module is at
http://www.python.org/doc/lib/module-gzip.html.
