Python time.perf_counter_ns() function gives the integer value of time in nanoseconds.
Syntax:
from time import perf_counter_ns
We can find the elapsed time by using start and stop functions. We can also find the elapsed time during the whole program by subtracting stoptime and starttime
Example 1:
Python3
# import perf_counter_ns() from time import perf_counter_ns # integer input from user, 2 input in single line n, m = map(int, input().split()) # Start the stopwatch / counter start = perf_counter_ns() for i in range(n): t = int(input()) # user gave input n times if t % m == 0: print(t) # Stop the stopwatch / counter stop = perf_counter_ns() print("Elapsed time:", stop, 'ns', start, 'ns') print("Elapsed time during the whole program", stop-start, 'ns') |
Output:
Example 2:
Python3
# import perf_counter_ns() from time import perf_counter_ns # integer input from user, 2 input in single line n, m = map(int, input().split()) # Start the stopwatch / counter start = perf_counter_ns() for i in range(n): t = int(input()) # user gave input n times if t % m == 0: print(t) # Stop the stopwatch / counter stop = perf_counter_ns() print("Elapsed time:", stop, 'ns', start, 'ns') print("Elapsed time during the whole program", stop-start, 'ns') |
Output:
