Suppose I have two dataframes d1 and d2
d1 = pd.DataFrame(np.ones((3, 3), dtype=int), list('abc'), [0, 1, 2])
d2 = pd.DataFrame(np.zeros((3, 2), dtype=int), list('abc'), [3, 4])
d1
0 1 2
a 1 1 1
b 1 1 1
c 1 1 1
d2
3 4
a 0 0
b 0 0
c 0 0
What is an easy and generalized way to interweave two dataframes' columns? We can assume that the number of columns in d2 is always one less than the number of columns in d1. And, the indices are the same.
I want this:
pd.concat([d1[0], d2[3], d1[1], d2[4], d1[2]], axis=1)
0 3 1 4 2
a 1 0 1 0 1
b 1 0 1 0 1
c 1 0 1 0 1
