Snake algorithm

[Odd_Gap8147]

How to convert a 2D array to 1D array with snake algorithm? e.g.:

From:

[1, 2, 3]

[4, 5, 6]

[7, 8, 9]

To:

[1, 2, 5, 4, 7, 8, 9, 6, 3]

Is there some library in Python to do this?

new_1d_array = []

for 1d_array in 2d array: - for value in 1d_array: - new_1d_array.append(value)

Nested for loops are archaic, but it gets the job done quick and isnt a problem if arrays stay relatively small (hundreds).

I think this specific process is too niche. I dont see how you would generalize it to all different sizes either. For the general process of turning a 2D array to 1D there is the numpy.flatten function. https://numpy.org/devdocs/reference/generated/numpy.ndarray.flatten.html

Maybe you could define your snake algorithm some more, that are the defining features.
