csv reading

I am using this command to import a csv file

Code:

temp = [[float(val) for val in row] for row in csv.reader(file('data.csv','rUb')) ]

this reads in my data as an array of the rows in my data. How do I change it so that my data is in an array of columns of my data? Mainly, I want to be able to easily find the max and min values of each column in my data after loaded into Vizard.

Hi,

Try the following code to transpose the list:

Code:

def transpose(m):

        return [[m[y][x] for y in range(len(m))]for x in range(len(m[0]))]



temp = transpose(temp)
