understanding TYPE in lsof output

Question

I opened a file through python. So, i did a lsof on the python process. output of lsof has the following line

COMMAND   PID    USER   FD   TYPE DEVICE SIZE/OFF       NODE NAME
python  15855 inaflash    3w   REG   0,25        0 4150810088 /home/inaflash/he.txt

Thing is, it has 3w. which means that the file is open for writing. But, i actually opened the file as follows

a = open('he.txt','r')

I read that, w means file is open for write. Can anyone help me understand why its w instead of r

Answer 1

I tried the same code in Python 3 and my file is opened in read mode.

Are you sure your file is the same opened with python and same python process ? Maybe you forgot to close the file somewhere in your code after opened it in write mode.

Edit: Also tried in Python 2, same result (read mode)
