Is there a way to access a numpy column by variable name?

Question

I'm trying to generate a bunch of graphs automatically but struggling with correctly using np.

Here's my code:

var1 = np.array(X.keys()[fs.get_support()])[0]
var2 = np.array(X.keys()[fs.get_support()])[1]

plt.scatter(new_data_2genre.var1, new_data_2genre.var2, c=new_data_2genre.c, alpha = 0.6, s=10)

When I run it I get an error from the new_data_2genre.var1 saying:

'DataFrame' object has no attribute 'var1'

Is there a way to plot var1 against var2?
