是否有更有效的方法在预先指定的箱中取平均数组？例如,我有一个数字数组和一个对应于该数组中bin开始和结束位置的数组,我想在这些数据库中取平均值？我有下面的代码,但我想知道如何减少和改进它.谢谢.

from scipy import *
from numpy import *

def get_bin_mean(a, b_start, b_end):
    ind_upper = nonzero(a >= b_start)[0]
    a_upper = a[ind_upper]
    a_range = a_upper[nonzero(a_upper < b_end)[0]]
    mean_val = mean(a_range)
    return mean_val


data = rand(100)
bins = linspace(0, 1, 10)
binned_data = []

n = 0
for n in range(0, len(bins)-1):
    b_start = bins[n]
    b_end = bins[n+1]
    binned_data.append(get_bin_mean(data, b_start, b_end))

print binned_data
