create variables in python with available data

Question

I have read a data like this:

import numpy as np
arr=n.loadtext("data/za.csv",delimeter=",")
display(arr)

Now the display looks like this:

array([[5.0e+01,1.8e+00,1.6e+00,1.75+e00],
       [4.8e+01,1.77e+00,1.63e+00,1.75+e00],
       [5.5e+01,1.8e+00,1.6e+00,1.75+e00],
       ...,
       [5.0e+01,1.8e+00,1.6e+00,1.75+e00],
       [4.8e+01,1.77e+00,1.63e+00,1.75+e00],
       [5.0e+01,1.8e+00,1.6e+00,1.75+e00]])

Now I would like to give this variables to this array

the first ist weight of person second is height of person third is height of mother fourth is height of father

Now I would like to now how can I create this variables that representin the columns?

Am I understanding correctly that you would like to be able to give the array columns some names? You might want to have a look at pandas.DataFrame which does essentially this. Alternatively, you could extract a single column into a new variable, e.g. weights = arr[:,0] — lucidbrot

install pandas library
import pandas as pd
use pd.read_csv("data/za.csv", columns= ["height", "weight", "etc"]) for read the data hope you get the solution.

As it has already been advised, you may use pandas.read_csv for the purpose as per below:

df = pd.read_csv(**{
    'filepath_or_buffer': "data/za.csv",
    'header': None,
    'names': ('weight_of_person', 'height_of_person', 'height_of_mother', 'height_of_father'),
})
