Importing float data from csv in python 2.7

Question

I have a csv file, which has one row with many data. The problem is that this data is float, something like this (7.66907027311089). I use this code to import this data:

with open('Sygnal2.txt','r') as csvfile:
    plots = csv.reader(csvfile, delimiter=',')
    for row in plots:
        y.append(int(float(row[0])))

Even when I use float, when I print y I got a list of no float numbers. Any ideas how to change it?

why int? Use y.append(float(row[0]))

You are converting twice - first you make a float from your string, and then an int from your float - simply do:

y.append(float(row[0]))
