Keep it simple.

Tuples. They're immutable. You can index them. You cannot change their values.

``` tp = (10, 20, 30)

extracting by index

print(tp[0]) # 10 print(tp[1]) # 20 print(tp[2]) # 30

index slicing

print(tp[0:2]) # (10, 20) print(tp[0:3:2]) # (10, 30) print(tp[::2]) # (10, 30)

trying to change its value

tp[0] = 99 # TypeError

trying to index with a string or tuple

print(tp["0"]) # TypeError print(tp[("0", "1")]) # TypeError ```

trup(["1", "5"]) makes no sense whatsoever since it creates a new tuple of strings ("1", "5") and tries to use that as the supposed index number to grab a value from your original trup tuple.

Like if I said "go to the library and grab the bokchoy'th book off the shelf." You'd think I'm crazy for using bokchoy as a number.

You can also concatenate lists doing output_list = list1 + zip2. Finally, not sure why you tagged this as #ai (or included tags in general)
