Question

I want to write something in a file.
for example,

fo=open('C:\\Python\\readline_test.txt','a')
for i in range(3):
 st='abc'+'\n'
 fo.write(st)
fo.close

then I open this python file in IDLE, and click “Run Module”.
There is no error message but I find the writing is not complete if I didn’t quit IDLE.
How can I complete the file writing without quitting the IDLE?
Thanks.

(I use Python 2.6.2 on Windows XP.)

Answer 1

You can try using

fo.flush()

and mayby

os.fsync()

after writing to file object to ensure that all file operations are flushed to disk.
