[ad_1] You can pair adjacent numbers, calculate the differences between the pairs, and determine that the list forms an arithmetic progression if the number of unique differences is no greater than 1: from operator import sub def progression(l): return len(set(sub(*p) for p in zip(l, l[1:]))) <= 1 so that: print(progression([3])) print(progression([7,3,-1,-5])) print(progression([3,5,7,9,10])) outputs: True True … Read more
