Usage

Counter example:

from pystat import Counter
counter = Counter()
counter.add()
assert 1 == int(counter)
counter.add()
assert 2 == int(counter)
counter.add(5)
assert 7 == int(counter)
assert 3 == len(counter)
assert 5.0 == counter.max
assert 1.0 == counter.min
assert 2.333.. == counter.mean
assert 2.309.. == counter.stddev

Timer example:

from pystat import Timer
timer = Timer()
timer.add(1.0)
assert 1 == int(timer)
timer.add(1.0)
assert 2 == int(timer)
timer.add(5)
assert 7 == int(timer)
assert (0.5, 0.95, 0.99) == timer.quantiles
assert 5.0 == timer.query(0.99)
assert 1.0 == timer.query(0.5)
