[Q] In-place file update with fileinput module

[Arsenal]

Hi,

I want to do some in-place editing with a text file. Initially i
didn't know the name that reference the file object "abc.txt". So i
did some testing and found that sys.stdout was redirected to
"abc.txt".

and hence the following piece of test code:

for line in fileinput.input(r'abc.txt', inplace=1):
    if line.find('replaceme') >= 0:
        #replace 'replaceme' with 'done'
        sys.stdout.write('done')
    else:
        #write the line unchanged
        sys.stdout.write(line)

Is this the right (or best) way to do it with "sys.stdout.write"?

Thanks!
