python Multithreading on single file

[snippsat]

You can not create a class like this.
If want want place funcrion in class look at @staticmethod.
Make no sense here so just remove the class.
Also to check that it works the time should be around 5-sec and not 10-sec.

# th.py
import threading
from time import sleep

def create_checksum(path):
    sleep(5)
    print("checksum Created")

def create_gzip(path):
    sleep(5)
    print("gzip_Created")

def main():
    path = "d:\\output\\abc.csv"
    # Call Checksum Function to generate Checksum no
    t1 = threading.Thread(target=create_checksum, args=(path,))
    t2 = threading.Thread(target=create_gzip, args=(path,))
    t1.start()
    t2.start()
    t1.join()
    t2.join()
    # both threads completely executed
    print("Done!")

if __name__ == "__main__":
    main()

Output:
===  python th.py ===
checksum Created
gzip_Created
Done!

Execution time: 5.228 s
