Python time.thread_time_ns() function is used to return the value of the sum of the system and user CPU time of the current thread. It is similar to time.thread_time() function. The difference is thread_time() function return the seconds of the CPU(Computer time) but  thread_time_ns() function return the nano-seconds of the CPU(Computer time)

Syntax:

time.thread_time_ns()

Return:

nanoseconds of the computer time

Example 1: Python program that uses thread_time_ns() function

# import time module
import time

# thread_time_ns() demo
print(time.thread_time_ns())

Output:

3633875824

Example 2: Python program that demonstrates thread_time_ns() function by sleeping some seconds

# import time module
import time

# thread_time_ns() demo
print(time.thread_time_ns())

# sleep for 10 seconds
time.sleep(10)

# thread_time_ns() demo
print(time.thread_time_ns())

# sleep for 2 seconds
time.sleep(2)

# thread_time_ns() demo
print(time.thread_time_ns())
# sleep for 2 seconds
time.sleep(2)

# thread_time_ns() demo
print(time.thread_time_ns())

Output:

3616352715
3616782418
3617173584
