You are completely right. Nevertheless, when I zip over arrays of different length, it is usually a bug instead of being intentional.
A code-golfed version for different array lengths:
np.c_[[a[:min(map(len,arrays))].T for a in arrays]].T
The trick to get a local variable within a list comprehension statement with
for l in [foo()]
from your zip_array function is very cool by the way, but I sacrificed it in favor of shorter code.
- PartiallyTyped 5y agoI like your your solution, I think using `a[0:min(map(len,arrays))]` (ie with 0) is faster because it returns a slice and not a copy of the array. I am glad you liked the trick!
