Gridspec, what am i doing wrong?

I am trying to create a 3x2 Plot with gridspec.
I have 3 plots that I want to arrange in this way:

Unfortunately this arrangement does not work with gridspec?
The ax2 plot is always drawn in only one field.

I use matplotlib V3.4.3

Many thanks for the help!

Here is my Code:

gs = gridspec.GridSpec(3, 2)
ax1 = plt.subplot(gs[0, 0])
ax2 = plt.subplot(gs[1:2, 0])
ax2.plot(x, y)
ax3 = plt.subplot(gs[:, 1])
ax3.plot(x, y)

gs[1:2, 0] is the same as gs[1,0]. Rather you want gs[1:3, 0] or gs[1:, 0]. You will find more info on slicing in numpy at: Indexing — NumPy v1.21 Manual
