Is it to remind yourself and your team to implement the class correctly? I don"t fully get the use of an abstract class like this:
class RectangularRoom(object):
def __init__(self, width, height):
raise NotImplementedError
def cleanTileAtPosition(self, pos):
raise NotImplementedError
def isTileCleaned(self, m, n):
raise NotImplementedError

How do I calculate percentiles with python/numpy?
1 answers
Is there a convenient way to calculate percentiles for a sequence or single-dimensional numpy array?
I am looking for something similar to Excel"s percentile function.
I looked in NumPy"s statistics reference, and couldn"t find this. All I could find is the median (50th percentile), but not something more specific.
Answer #1
You might be interested in the SciPy Stats package. It has the percentile function you"re after and many other statistical goodies.
percentile() is available in numpy too.
import numpy as np
a = np.array([1,2,3,4,5])
p = np.percentile(a, 50) # return 50th percentile, e.g median.
print p
3.0
This ticket leads me to believe they won"t be integrating percentile() into numpy anytime soon.
