Python numpy.arange()用法及代码示例

关于：
arange([start，] stop [，step，] [，dtype])：返回一个数组，该数组具有按间隔均匀分布的元素。提到的间隔是打开的一半，即[开始，停止]
参数：

start : [optional] start of interval range. By default start = 0
stop  : end of interval range
step  : [optional] step size of interval. By default step size = 1,  
For any output out, this is the distance between two adjacent values, out[i+1] - out[i]. 
dtype : type of output array

返回：

Array of evenly spaced values.
Length of array being generated  = Ceil((Stop - Start) / Step)

# Python Programming illustrating 
# numpy.arange method 
  
import numpy as geek 
  
print("A\n", geek.arange(4).reshape(2, 2), "\n") 
  
print("A\n", geek.arange(4, 10), "\n") 
  
print("A\n", geek.arange(4, 20, 3), "\n")

输出：

A
 [[0 1]
 [2 3]]

A
 [4 5 6 7 8 9]

A
 [ 4  7 10 13 16 19]
