write array in python

Question

I have a csv file that contains a list of data points.

1.3
5.0
15.35
14.3
9.8
4.4
7.6
9.87

How can I write a python program that can read the numbers in the csv file and make them into an array x so that:

x=[1.3,5.0,15.35,14.3,9.8,4.4,7.6,9.87]

?

Answer 1

You can use inbuilt genfromtext method from numpy.
More info on numpy.genfromtext is here

Demo Code:

import numpy as np
x= np.genfromtxt ('youData.csv', delimiter=",")
print x

Output:

Python 2.7.9 (default, Dec 10 2014, 12:24:55) [MSC v.1500 32 bit (Intel)] on win32
Type "copyright", "credits" or "license()" for more information.

Answer 2

Or the easiest solution in my experience and fastest CSV reading:

import pandas as pd
import numpy as np
x=pd.read_csv('file.csv', header=None)
x=np.array(x.values)
