Python write to a file returns empty file

Question

I am trying to do simple commands to write hello world to a file:

50 complexity:test% python2.7
Python 2.7.3 (default, Feb 11 2013, 12:48:32)
[GCC 4.4.6 2012         


        

Answer 1

You need to close the file:

>>> f.close()

Also, I would recommend using the with keyword with opening files:

with open("/export/home/vignesh/resres.txt","w") as f:
    f.write("hello world") 
    f.write("\t".join(["hello","world"]))

It will automatically close them for you.
