How to adjust subplots spacing and to place y labels in matplotlib?

I have to use matplotlib to produce the following layout.

fig = plt.figure(figsize=(15,9))

for i in range(3):

    ax = plt.subplot2grid((3, 5), [i, 0], 1, 1 )

for i in range(3):

    ax = plt.subplot2grid((3, 5), [i, 1], 1, 1 )

for i in range(3):

    ax = plt.subplot2grid((3, 5), [i, 2], 1, 3 )

enter image description here
I'd like to add some space between second and third columns to place a common ylabel indicated by the red marker. I got stuck at this point. Anyone can give me some guidance? Thank you!

If your label is not long, you can simply add it to the middle graph and use tight_layout to format it:

fig = plt.figure(figsize=(15,9))

for i in range(3):

    ax = plt.subplot2grid((3, 5), [i, 0], 1, 1 )

for i in range(3):

    ax = plt.subplot2grid((3, 5), [i, 1], 1, 1 ) 

for i in range(3):

    ax = plt.subplot2grid((3, 5), [i, 2], 1, 3 )

    if i == 1:

        ax.set_ylabel("label for all")



plt.tight_layout()

plt.show()

This will not work for very long labels, though, because tight_layout will misinterpret the height of the middle row. In this case, we can simply replace the text with the longer version afterwards:

fig = plt.figure(figsize=(15,9))

for i in range(3):

    ax = plt.subplot2grid((3, 5), [i, 0], 1, 1 )

for i in range(3):

    ax = plt.subplot2grid((3, 5), [i, 1], 1, 1 ) 

for i in range(3):

    ax = plt.subplot2grid((3, 5), [i, 2], 1, 3 )

    if i == 1:

        mylabel = ax.set_ylabel("dummy")



plt.tight_layout()



mylabel.set_text("not a dummy any more but a very very very loooooooooooooooooong label")

plt.show()
