I am plotting a graph using plt.plot using information found online.
However, I do not know what the y[:,0] means:
plt.plot(t, y[:,0], label= 'active Mos')
Similarly, I see y[:,1] a lot too...
plt.plot is to plot a line to the graph, right?
It is a notation used in Numpy/Pandas.
[ : , 0 ] means (more or less) [ first_row:last_row , column_0 ].
If you have a 2-dimensional list/matrix/array, this notation will give you all values in column 0 (from all rows).
