*cpyquickhelper* is a template to create a module with
C functions in different ways. It implements function
*measure_time*:

::

    from cpyquickhelper.numbers import measure_time
    from math import cos

    res = measure_time("cos(x)", context=dict(cos=cos, x=5.))
    print(res)

::

    {'average': 3.909366205334663e-06, 'deviation': 6.238702219064397e-07,
     'min_exec': 3.635883331298828e-06, 'max_exec': 5.776062607765198e-06,
     'repeat': 10, 'number': 50, 'context_size': 240}

It also implements an event profiler: it logs the timestamp
for every event such as functions call or returns, memory allocations.

::

    import io
    import numpy
    from cpyquickhelper.profiling import EventProfiler

    def custom_array(N):
        a = numpy.zeros((N, N))
        a[:, 0] = 1
        a[0, :] = 1
        return a

    ev = EventProfiler(impl='c')
    ev.start()

    custom_array(3)

    ev.stop()

    df = ev.retrieve_results()  # DataFrame
    st = io.StringIO()
    df.to_csv(st, index=False)
    print(st.getvalue().replace("\r", ""))
