Let’s see how to use Numpy genfromtxt function.

Numpy genfromtxt function python

Using genfromtxt method

Numpy genfromtxt function let you load file content to your Python code. I’m doing 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)

os.chdir gives the possibility to set source catalog. If not set genfromtxt function will use current catalog.

  • The first one is file name.
  • Thanks to dtype I’m able to set data type. Remeber that it should be type dedicated to numbers.
  • Delimiter in my example is a come because the file it is csv file.
  • numpy, os Tags:genfromtxt
