Changing strings to floats in an imported .csv

Question

Quick question for an issue I haven\'t managed to solve quickly:

I\'m working with a .csv file and can\'t seem to find a simple way to convert strings to floats. Her

Answer 1

Try something like the following

import csv

def read_lines():
    with open('testdata.csv', 'rU') as data:
        reader = csv.reader(data)
        for row in reader:
            yield [ float(i) for i in row ]

for i in read_lines():
    print(i)

# to get a list, instead of a generator, use
xy = list(read_lines())

As for the easiest way, then I suggest you see the xlrd, xlwt modules, personally I always have hard time with all the varying CSV formats.
