Python write in mkstemp() file

Question

I am trying to write in this file :

file          


        

Answer 1

mkstemp() returns a tuple with a file descriptor and a path. I think the issue is that you're writing to the wrong path. (You're writing to a path like '(5, "/some/path")'.) Your code should look something like this:

from tempfile import mkstemp

fd, path = mkstemp()

# use a context manager to open the file at that path and close it again
with open(path, 'w') as f:
    f.write('TEST\n')

# close the file descriptor
os.close(fd)
