Python查找Numpy数组列表的平均值

给定一个Numpy数组的列表，任务是找到每个numpy数组的平均值。让我们看看有几种方法可以完成这个任务。

方法#1：使用np.mean()

# Python code to find mean of every numpy array in list
  
# Importing module
import numpy as np
  
# List Initialization
Input = [np.array([1, 2, 3]),
         np.array([4, 5, 6]),
         np.array([7, 8, 9])]
  
# Output list initialization
Output = []
  
# using np.mean()
for i in range(len(Input)):
   Output.append(np.mean(Input[i]))
  
# Printing output
print(Output)

输出:

[2.0, 5.0, 8.0]

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 = []
  
# using np.mean()
for i in range(len(Input)):
   Output.append(np.average(Input[i]))
  
# Printing output
print(Output)
