In future please copy and paste the entire traceback. It appears that 
you typed in just one line of it.


In this case the line raising the exception was obvious, but often it is 
not.

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,

You are sending the actual file objects to shutil.move, it is expecting
a string. Actually, strings containing the path to move and the
destination. Like this: shutil.move('/tmp/file2', '/tmp/file1')

snipped

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.
