How to use Numpy genfromtxt function?

Let’s see how to use Numpy genfromtxt function.

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.

Genfromtxt Numpy function is having various parameters.

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.

How to set the skiprows parameter

The skiprows parameter allows you to skip a specified number of rows at the beginning of the file. This can be useful if the file contains header rows or other rows that you do not want to load.
