Przykład funkcji Python Numpy Reshape

# Welcome to softhunt.net
# Python Program illustrating
# numpy.reshape() method
 
import numpy as np
 
# array = np.arrange(8)
# The 'numpy' module has no attribute 'arrange'
array1 = np.arange(8)
print("Original array : \n", array1)
 
# shape array with 3 rows and 3 columns
array2 = np.arange(8).reshape(2, 4)
print("\narray reshaped with 2 rows and 4 columns : \n",
      array2)
 
# shape array with 4 rows and 2 columns
array3 = np.arange(8).reshape(4, 2)
print("\narray reshaped with 4 rows and 2 columns : \n",
      array3)
 
# Constructs 3D array
array4 = np.arange(8).reshape(2, 2, 2)
print("\nOriginal array reshaped to 3D : \n",
      array4)
