Python time process clock() revisits the existing processor time as a hovering point number articulated in seconds on Unix. The exactitude depends on that of the C meaning of the same first name, however, in any casing, this is the purpose to employ for benchmarking Python or timing algorithms.
On Windows, this purpose revisits wall-clock seconds passed while the first call to this purpose, as a floating-point numeral, anchored in the Win32 function QueryPerformanceCounter.
Following is the syntax for asctime() method:
This method returns the current processor time as a floating-point number expressed in seconds on Unix and in Windows it returns wall-clock seconds elapsed since the first call to this function, as a floating-point number.
The following example shows the usage of clock() method.
#!/usr/bin/python import time def procedure(): time.sleep(2.5) # measure process time t0 = time.clock() procedure() print time.clock(), "seconds process time" # measure wall time t0 = time.time() procedure() print time.time() - t0, "seconds wall time"
When we run the above program, it produces the following result:
0.0 seconds process time 2.50023603439 seconds wall time
