I have 3 arrays, each have an x and y column and I need to extend each row
with the additional rows from the other arrays. Only one of the arrays has
all the x,y values. I am also not sure how to deal with the missing values.
I was thinking about making an array full of nan. So for example if I have
>>> bb
array([['1', '1', 'apple', 'pie'],
['2', '5', 'boys', 'play']],
dtype='|S8')
>>> aa
array([[1, 1,free],
[1, 2,upgrade],
[1, 3, down],
[2, 4, left],
[2, 5, right],
[2, 6, now]])
and I what to end up with
magicfunc(aa,bb)
array([[1, 1, free, 'apple', 'pie'],
[1, 2, upgrade, '', ''],
[1, 3, down, '', ''],
[2, 4, left, '', ''],
[2, 5, right, 'boys', 'play'],
[2, 6, now, '', '']])
Whats the "right" way to do this, I have several ideas but I can't be the
first to do this. I know the dimensions of the final array. but don't really
have a plan of where to go from there.
