How to put individual tags for a matplotlib scatter plot?

I am trying to do a scatter plot in matplotlib and I couldn’t find a way to add tags to the points. For example:

scatter1=plt.scatter(data1["x"], data1["y"], marker="o",
                     c="blue",
                     facecolors="white",
                     edgecolors="blue")

I want for the points in “y” to have labels as “point 1”, “point 2”, etc. I couldn’t figure it out.
