list comprehension - Numpy - Late Binding Closures

Question

I guess it could be a late binding closures problem.

for i,dt in enumerate(delay_list):
    accel[:,i],freq[:,i] = srs(sum)

What I actually get: 2 arrays (shape: 124,3) with all 3 columns identical (corresponding to i=2) What I expect: 2 arrays (shape: 124,3) with each column corresponding to i=0,1,2

Additional info:

srs(sum) is a function that loads a txt file (sum) with a filename that changes in accordance with the dt index.

This is my first post. I apologize in case of wrong formatting.
