What happens if I log into the same file from multiple different processes in python?

Question

I spent hours to dig the behavior, first about those questions:

• Atomicity of `write(2)` to a local filesystem
• How can I synchronize -- make atomic -- writ

Answer 1

I have tried a similar code like this(I have tried in python 3)

import threading
for i in range(0,100000):
     t1 = threading.Thread(target= funtion_to_call_logger, args=(i,))
     t1.start()

This worked completely fine for me, similar issue is addressed here.

This took a lot of Cpu time but not memory.

EDIT:
Fine means all the requested things were logged but Order was missing.Hence Race condition still not fixed ,
