Seems reasonable to me. Sometimes the simple things are the best.

The only thing I'd do is pre-process the "all" case:


lst = [100,101,102,103]
indexes = input("'Enter indexes': ").split(",")
if indexes == ["all"]:
    indexes = list(range(len(lst))
if indexes == [""]:
    print("Done")
else:
    indexes = [int(k) for k in indexes]
    print(indexes) 
    for i in indexes:
        print(lst[i])
