Python time clock() Function
Description:
On Unix, this function returns the current processor time as a floating point number expressed in seconds. The precision depends on that of the C function of the same name, but in any case, this is the function to use for benchmarking Python or timing algorithms.
On Windows, this function returns wall-clock seconds elapsed since the first call to this function, as a floating point number, based on the Win32 function QueryPerformanceCounter.
Syntax:
Parameters:
Here is the detail of parameters:
Example:
#!/usr/bin/python
import time
def procedure():
time.sleep(2.5)
# measure process time
t0 = time.clock()
procedure()
print time.clock() - t0, "seconds process time"
# measure wall time
t0 = time.time()
procedure()
print time.time() - t0, "seconds wall time"
|
This produces following result:
0.0 seconds process time
2.50023603439 seconds wall time
|
Note: Not all systems can measure the true process time. On such systems (including Windows), clock usually measures the wall time since the program was started.
