# Correlation between specific columns of a data set

I have a CSV file which has 150 columns belonging to 7 categories but I want a correlation between 2 categories. The categories are movies and music, 12 and 19 columns respectively.

Is there a way to plot a correlation matrix or a correlation graph between two of the categories and selected columns?

For example, 19 columns on x and 12 columns on y. Or summing 12 and 19 columns and having a correlation between only 31 columns instead of 150.

I'm using Python. Which packages could help me?

from matplotlib import cm
