如何在python中生成随机范围？

Question

I want to generate a random arange of 10 values in Python. Here's my code. Is there any faster way or more elegant way to generate it ? Because the x in function lambda is actually never used.

>>> import numpy as np
>>> import random as rd
>>> i = np.arange(0, 10)
>>> noice = map(lambda x: rd.random(), i)
>>> i
array([0, 1, 2, 3, 4, 5, 6, 7, 8, 9])
>>> noice
[0.040625208925370804, 0.3979391267477529, 0.36389993607597815, 0.5222540865995068, 0.4568532903714069, 0.9028000777629279, 0.6011546913245037, 0.4779160505869603, 0.9929389966510183, 0.7688424310182902]

You can simply use np.random.rand(10) .

See the NumpPy docs .
