With your original code, the elements of array2 are strings, and here
Python is refusing to multiply the string x[a] by the complex number W
[n % N]. Presumably you want the elements of array2 to be integers or
floats instead? (Your comments suggest integers, though I think floats
would be more natural here.)
MRAB's earlier reply suggests how to fix this:
array2 = []
for a in range(len(array)):
array2.append(int(array[a])) # note the extra int!
That works, but the code is cleaner if you iterate over the elements
of the array directly, instead of over their indices:
array2 = []
for x in array:
array2.append(int(x))
There are other ways, too: a seasoned Python user would probably
write this either as a list comprehension:
array2 = [int(x) for x in array]
... or using the built-in map function:
array2 = map(int, array)
