Confused in Threading?

This is exactly what happens with the print function and the system standard output. The output, like BAL is written to the standard output, then the output is flushed, with a newline character. This is why you see inconsistent spacing and team names running together, like this:

Now, consider the following code:

import threading

def worker():
    print ('Hello World') 

thread_list = []
for i in range(4):
    thread = threading.Thread(target=worker)

No matter how many times I run this program newlines are not getting flushed. Why?


Hello World
Hello World
Hello World
Hello World
