Question

I am trying to read from one file and write to another file using:

with open('example2') as inpf, open('outputrt','w') as outf:  
    for l in inpf:
        outf.write(l)  

But I am getting a syntax error at the line 1 i.e.

"with open('example2') as inpf, open('outputrt','w') as outf:" pointing at "inpf,"

My python version is 2.6. Is there an error in syntax?

Answer 1

That syntax is only supported in 2.7+.
In 2.6 you can do:

import contextlib

with contextlib.nested(open('example2'), open('outputrt','w')) as (inpf, outf):  
    for l in inpf:
        outf.write(l) 

Or it might look cleaner to you to do this (this would be my preference):

with open('example2') as inpf:
    with open('outputrt','w') as outf:  
        for l in inpf:
            outf.write(l)
