How to check whether a file is_open and the open_status in python

Question

Is there any python functions such as:

filename = \"a.txt\"
if is_open(filename) and open_status(filename)==\'w\':
   print filename,\" is open for writing\"         


        

Answer 1

I think the best way to do that is to try.

def is_already_opened_in_write_mode(filename)
     if os.path.exists(filename):
         try:
             f = open(filename, 'a')
             f.close()
         except IOError:
             return True
     return False
