time.time() to measure the elapsed wall-clock time between two points:
import time start = time.time() print("hello") end = time.time() print(end - start)
This gives the execution time in seconds.
Another option since Python 3.3 might be to use
process_time, depending on your requirements. Before 3.3 it was recommended to use
time.clock (thanks Amber). However, it is currently deprecated:
On Unix, return the current processor time as a floating point number
expressed in seconds. The precision, and in fact the very definition
of the meaning of “processor time”, depends on that of the C function
of the same name.
On Windows, this function returns wall-clock seconds elapsed since the
first call to this function, as a floating point number, based on the
QueryPerformanceCounter(). The resolution is typically
better than one microsecond.
Deprecated since version 3.3: The behaviour of this function depends
on the platform: use
depending on your requirements, to have a well defined behaviour.
