AFAIK it is not necessay in P3 - I will run tests as soon as I am able.

This is only true for files open for reading. And even then it is simply good practice to wrap file access in:

with open(filename, mode) as filehandle:
    for line in filehandle:
        print(line)
        ...
        print("teststring", file=filehandle)

Read the docs if you need to know why. Your own test may only cover a fraction of the wisdom found in the Python documentation :)
