NumPy: Save a given array to a text file and load it
NumPy: Basic Exercise-37 with Solution
Write a NumPy program to save a given array to a text file and load it.
Sample Solution :
Python Code :
import numpy as np import os x = np.arange(12).reshape(4, 3) print("Original array:") print(x) header = 'col1 col2 col3' np.savetxt('temp.txt', x, fmt="%d", header=header) print("After loading, content of the text file:") result = np.loadtxt('temp.txt') print(result)
Original array: [[ 0 1 2] [ 3 4 5] [ 6 7 8] [ 9 10 11]] After loading, content of the text file: [[ 0. 1. 2.] [ 3. 4. 5.] [ 6. 7. 8.] [ 9. 10. 11.]]
