python怎么创建数组

#coding=utf-8import numpy as np

a = np.array([1,2,3,4,5])print a

b = np.zeros((2,3))print b

c = np.arange(10)print c

d = np.arange(2,10,dtype=np.float)print d

e = np.linspace(1.0,4.0,6)print e

f = np.indices((3,3))print f

a = []

a.append((1,2,4))

a.append((2,3,4))

a = np.array(a)

a.flatten()

import numpy as np

mylist = [1,2,3]print tuple(mylist)

iarray = np.array(tuple(mylist))print iarray
