Difference between reshape() and resize() method in Numpy

Both the numpy.reshape() and numpy.resize() methods are used to change the size of a NumPy array. The difference between them is that the reshape() does not changes the original array but only returns the changed array, whereas the resize() method returns nothing and directly changes the original array.

Example 1: Using reshape()

Python3

# importing the module
import numpy as np

# creating an array
gfg = np.array([1, 2, 3, 4, 5, 6])
print("Original array:")
display(gfg)

# using reshape()
print("Changed array")
display(gfg.reshape(2, 3))

print("Original array:")
display(gfg)

Output:

Example 2: Using resize()

Python3

# importing the module
import numpy as np

# creating an array
gfg = np.array([1, 2, 3, 4, 5, 6])
print("Original array:")
display(gfg)

# using resize()
print("Changed array")
# this will print nothing as None is returned
display(gfg.resize(2, 3))

print("Original array:")
display(gfg)

Output:
