In this tutorial, I will show you how to convert a list to a numpy array in python.
The first thing we need to do is import the numpy module. This module is used for scientific computing and it has a lot of useful functions for data analysis.
import numpy as npconvert list to numpy array
| listData = [1, 2, 3] | |
| npArrData = np.asarray(listData) | |
| print("listData:", type(listData), ": ", listData) | |
| print("npArrData: ", type(npArrData), ": ", npArrData) | |
| # Output | |
| # listData: <class 'list'> : [1, 2, 3] | |
| # npArrData: <class 'numpy.ndarray'> : [1 2 3] |
convert numpy array to list
| npArrData = np.array([1, 2, 3]) | |
| listData = npArrData.tolist() | |
| print("npArrData: ", type(npArrData), ": ", npArrData) | |
| print("listData:", type(listData), ": ", listData) | |
| # Output | |
| # npArrData: <class 'numpy.ndarray'> : [1 2 3] | |
| # listData: <class 'list'> : [1, 2, 3] |
