Learn to reshape NumPy arrays in 4 minutes! ↔️

#python #coding #numpy # reshape() = Changes the shape of an array # w/o altering its underlying data # array.reshape(rows, columns) import numpy as np array = np.array([1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12]) array = array.reshape(2, 6) array = array.reshape(3, 4) # array = array.reshape(4, 4) # Too many elements # array = array.reshape(2, 4) # Too few elements array = array.reshape(4, 3) array = array.reshape(2, 2, 3) # 3D array = array.reshape(3, 2, 2) # 3D # -1 NumPy will automatically infer the correct size for that dimension array = array.reshape(1, -1) array = array.reshape(-1, 1) print(array)
