Python | Find average value of list Numpy Array



Method # 1: Using np.mean ()

# Python code to find the average of each array in the list

 
# Import Module

import numpy as np

 
# Initialization list

Input = [np.array ([ 1 , 2 , 3 ]),

np.array ([ 4 , 5 , 6 ]),

np.array ([ 7 , 8 , 9 ])]

  
# Initialize the output list

Output = []

 
# using np.mean ()

for i in range ( len ( Input )):

  Output.append (np.mean ( Input [i]) )

 
# Printout

print (Output)

Exit:

 [2.0, 5.0, 8.0] 

Method # 2: Using np.average ()

# Python code to find the average
# each numpy array in the list

 
# Importer

import numpy as np

 
# Initialization list

Input = [np.array ([ 11 , 12 , 13 ]),

  np.array ([ 14 , 15 , 16 ]),

np.array ([ 17 , 18 , 19 ] )]

 
# Initialize the output list

Output =  []

 
# using np.mean ()

for i in range ( len ( Input )):

Output.append (np.average ( Input [i]))

 
# Printout

print (Output)

Output:

 [12.0, 15.0, 18.0]
