I want to merge two arrays in python in a special way. The entries with an odd index of my output array `out`

shall be the coresponding entries of my first input array `in0`

. The entries with an even index in `out`

shall be the coresponding entries of my second input array `in1`

.

`in0`

, `in1`

and `out`

are all the same length.

Example:

The input arrays

`in0 = [0, 1, 2, 3] in1 = [4, 5, 6, 7] `

shall be merge to the output array

`out = [0, 5, 2, 7] `

Is there a nicer way than to loop over the whole length of the inputs and fill my `out`

'by hand'?

You could use a list comprehension and select values from `in0`

on even indices and `in1`

on odd indices:

`[in0[i] if i % 2 == 0 else in1[i] for i in range(len(in0))] # [0, 5, 2, 7] `
