# numpy.testing.measure

testing.measure(code_str, times=1, label=None)

  Return elapsed time for executing code in the namespace of the caller.

  The supplied code string is compiled with the Python builtin `compile`. The precision of the timing is 10 milli-seconds. If the code will execute fast on this timescale, it can be executed many times to get reasonable timing accuracy.

  Parameters
    code_str str

      The code to be timed.

    times int, optional

      The number of times the code is executed. Default is 1. The code is only compiled once.

    label str, optional

      A label to identify code_str with. This is passed into `compile` as the second argument (for run-time error messages).

  Returns
    elapsed float

      Total elapsed time in seconds for executing code_str times times.

  Examples

      >>> times = 10
      >>> etime = np.testing.measure('for i in range(1000): np.sqrt(i**2)', times=times)
      >>> print("Time for a single execution : ", etime / times, "s")
      Time for a single execution :  0.005 s
