[New-bugs-announce] [issue39581] Python Interpreter Doesn't Work Well In Thread Class

[임수진학부생]

New submission from 임수진학부생 <21600590 at handong.edu>:

================================================================
import threading
import time

def threadFunc():
    while True:
        print('new thread')
        time.sleep(2)
def main():
    th = threading.Thread(target=threadFunc())
    th.start()
    while True:
       print('main Thread')
       time.sleep(1)
    th.join()
 
if __name__ == '__main__':
   main()
==============================================================

When I run the above code in python 3.7, it works in unexpected way.

I expected this code causes an syntax error for giving an improper argument to parameter because I gave "threaFunc()" not "threaFun" as an argument of target in Thread class. However, this code executes a function "threadFunc()" as a general function not thread.
