Need help with file object

[Unix SA]

Hello,

I am facing some issue when copying or moving file

f=open('/tmp/file1')
s=open('/tmp/file2')

for line in f:
if 'match' not in line:
s.write(line)

import shutil
shutil.move(s, f)

With above prog I am getting error
TypeError: coercing to Unicode: need sting or buffer, file found

What that means and how I can resolve it.

Regards,
Dj

s=open('/tmp/file2')

s.write(line)

Among other things you are missing a write mode

(2nd optional argument to open)

shutil.move() expects filename arguments, not open file objects.

Also, since your open() statements are missing the file mode ('r' or 'w'),
they will both open in the default read mode.

Also, it really helps if you post the real code and real error message.
Don't type them from memory.
