create & read from tempfile

Question

Is there anyway I could write to tempfile and include it in a command, and then close/remove it. I would like to execute the command, eg: some_command /tmp/some-temp-file.
Many thanks in advance.

import tempfile temp = tempfile.TemporaryFile() temp.write('Some data') command=(some_command temp.name) temp.close() 

Answer 1

Complete example.

import tempfile with tempfile.NamedTemporaryFile() as temp:     temp.write('Some data')     if should_call_some_python_function_that_will_read_the_file():        temp.seek(0)        some_python_function(temp)     elif should_call_external_command():        temp.flush()        subprocess.call(["wc", temp.name]) 

Update: As mentioned in the comments, this may not work in windows. Use this solution for windows

Update 2: Python3 requires that the string to be written is represented as bytes, not str, so do instead

temp.write(bytes('Some data', encoding = 'utf-8'))
