Using genfromtxt method

The NumPy genfromtxt function lets you load file content into your Python code. I’m using genfromtxt like this:

import numpy as np
import os

os.chdir("C:/Users/Pythoneo/Documents/MyProjects")

a = np.genfromtxt("data.csv", dtype='float', delimiter=',')
print(a)

chdir allows setting the working directory. If not set, the genfromtxt function will use the current directory.
