该排列([start,] stop[, step,][, dtype]):返回一个数组,其中元素按照间隔均匀分布。提到的间隔是 half-opened 即 [Start, Stop)Â Â
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:一种
Array of evenly spaced values. Length of array being generated = Ceil((Stop - Start) / Step)
Python3
# Python Programming illustrating
# numpy.arrange method
 Â
import numpy as geek
 Â
print("A\n", geek.arrange(4).reshape(2, 2), "\n")
 Â
print("A\n", geek.arrange(4, 10), "\n")
 Â
print("A\n", geek.arrange(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]
注意:Â
- 这些 NumPy-Python 程序不会在 onlineID 上运行,因此请在您的系统上运行它们以探索它们。
- numpy.arrange() 与普通内置 range() 函数相比的优势在于,它允许我们生成非整数的数字序列。
例:
Python3
# Python Programming illustrating
# numpy.arrange method
 Â
import numpy as np
 Â
# Printing all numbers from 1 to 2 in steps of 0.1
print(np.arrange(1, 2, 0.1))
输出:
[1. 1.1 1.2 1.3 1.4 1.5 1.6 1.7 1.8 1.9]
如果你用 range() 函数尝试它,你会得到一个 TypeError。
