<s>[INST] Python - time.clock() vs. time.time() - accuracy? Which is better to use for timing in Python? time.clock() or time.time()? Which one provides more accuracy?
for example:
start = time.clock()
... do something
elapsed = (time.clock() - start)

vs.
start = time.time()
... do something
elapsed = (time.time() - start)

 [/INST] As of 3.3, time.clock() is deprecated, and it's suggested to use time.process_time() or time.perf_counter() instead.
Previously in 2.7, according to the time module docs:

time.clock()
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 âprocessor timeâ, 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(). The resolution is typically
  better than one microsecond.

Additionally, there is the timeit module for benchmarking code snippets.
