Writing to a file and function

I have a code similar to:

'''
This is main file
'''

path_to_file = './sample.txt'
config_file = open(path_to_file, 'a')
import functions_write as function
a = 1
if a== 1:
    config_file.write("Hello World\n")
    function_text = "Hi World\n"
    function.write_function(function_text, path_to_file)
#

Another file for writing functions functions_write.py

def write_function(text_write, path_to_file):
    config_file = open(path_to_file, 'a')
    config_file.write(text_write)
    config_file.close()

#################################################################

I had expected it would write in order

Hello World Hi World

But it is writing as: Hi World Hello World

Any thoughts on why it is writing the function first in the file.

Thanks

You shouldn't generally have two open write file descriptors to a file as you do. What's happening here is that writes are buffered until something causes them to get flushed. In this case you explicitly call the close in write_function so it is called (and that write gets flushed) first. The first write isn't flushed until the close on its file descriptor is implicitly closed when your program exits.
