方法二:使用np.average()。# Python code to find mean of # every numpy array in list # Importing module import numpy as np # List Initialization Input = [np.array([11, 12, 13]), np.array([14, 15, 16]), np.array([17, 18, 19])] # Output list initialization Output = [] # ...
average = np.mean(sub_arr) 打印结果:将平均值打印出来。 代码语言:txt 复制 print("指定部分的平均值为:", average) 完整代码示例: 代码语言:txt 复制 import numpy as np arr = np.array([1, 2, 3, 4, 5, 6, 7, 8, 9, 10]) start_index = 2 end_index = 6 sub_arr = arr[start_i...
# find the average of entire arrayaverage1 = np.average(array1)# find the average across axis 0average2 = np.average(array1,0)# find the average across axis 0 and 1average3 = np.average(array1, (0,1)) print('\naverage of the entire array:', average1)print('\naverage across ax...
Get the average of array # Along axis = 0 arr2 = np.average(arr, axis=0) # Example 4: Get the average of array # Along axis = 1 arr2 = np.average(arr, axis=1) # Example 5: Get the average with weights # To average along axis = 0 arr2 = np.average(arr, axis=0, weight...
Python numpy.array2string函数方法的使用 numpy.array2string 函数用于将 NumPy 数组转换为字符串表示。它允许你自定义输出格式,包括精度、分隔符、行和列的宽度等。本文主要介绍一下NumPy中array2string方法的使用。 numpy.array2string numpy.array2string(a, max_line_width=None, precision=None, suppress_small...

指数移动平均线(exponential moving average)是另一种技术指标。指数移动平均线使用的权重是指数衰减的。对历史数据点赋予的权重以指数速度减小,但不会到达0。在计算权重的过程中使用 exp 和 linspace 函数。 1)先了解numpy中的exp 和 linspace 函数 x = np.arange(5)y = np.arange(10)print ("Exp", np.exp...
