Read in multiple columns to one variable

Question

I have a file with 13 columns, I want the first column to be one variable which I have and I want all the other 12 to be put together so I can get their mean and other measurements as well as turn them into a histogram. I have it so I can get the first like I said and one of the columns but how do I modify this code to include all 12 columns in y?

What I have tried:

import numpy as np

data = np.loadtxt("EP305Formal2.txt",float,skiprows=1)

xcol, ycol = 0, 12
x, y = data[:,xcol], data[:,ycol]


print(y)

Solution 1

You only need to declare the column where the split occurs:

Python

xx = 1 # break at column 1
x, y = data[:xx], data[xx:] # x gets first column, y gets the rest
print ("X: ", x)
print ("Y: ", y)

And you do not want those extra commas in the slice definitions.
