Note that you can write this without Python loop as
v = np.arange(0, 4, 0.1)
f = v**2 * np.exp(-v**2)

I want to use Alan's (and others') idea to run a SQL file to create a
table if that table does not exist. Alan suggested using
executescript() to do this. I misunderstood Alan and thought that
this would take a filename and execute it. Instead, it appears that I
must pass to it a string which

There are two problems here.
The first is that you need a space after the def.
