This problem comes from part of a solution of LeetCode for rotated array.
Suppose an array sorted in ascending order is rotated at some pivot
unknown to you beforehand.
(i.e., [2,3,5,6,7,8,12] might become [6,7,8,12,2,3,5]).
(And we just want to find the "rotation point" here, whi...

I'm trying to reshape my input arrays in a way that's described below to be able to fit a curve on the data points, plot it, etc.
It works fine, but I'm afraid it's not the most efficient way of doing it, and also it's hard to understand and read. It's part of a bigger function, but I only post ...
Frequently input for problems is given as a 1D or 2D array in a text file.
Have knocked out a method to do so, but believe something shorter, clearer and cheaper can be written:
def read_array_from_txt(path, dim, typ, sep):
'''
@time: O(n)
@space: O(n)

Lacking answers, I've suggested an edit to the api tag to clarify its intended usage (code that implements and/or wraps an API, not code that uses one). Feel free to improve it further along those lines.
