What is the pythonic way to write strings to file?

Question

What's the difference between using File.write() and print>>File,?

Which is the pythonic way to write to file?

>>> with open('out.txt','w') as fout:
...     fout.write('foo bar')
... 

>>> with open('out.txt', 'w') as fout:
...     print>>fout, 'foo bar'
... 

Is there an advantage when using print>>File, ?

Answer 1

write() method writes to a buffer, which (the buffer) is flushed to a file whenever overflown/file closed/gets explicit request (.flush()).

print will block execution till actual writing to file completes.

The first form is preferred because its execution is more efficient. Besides, the 2nd form is ugly and un-pythonic.
