The built-in Python function slice allows the programmer to select portions of the input that they want to slice out. It has two possible syntaxes, slice(stop) or slice(start, stop, step). In the single parameter version, start and step default to none. The following code will print “Str”.

Responses

s1 = slice(2,6)
s1 = slice(2,6)

s1 = slice(1, 5)
s1 = slice(1, 5)

s1 = slice(1, 5, 2)
s1 = slice(1, 5, 2)

s1 = slice(2, 6, 2)

Answer 1

To determine which of the provided options will result in the string "ti" when applied to the string String = 'String slicing', we can analyze each option.

1. s1 = slice(2, 6)

   • This will slice from index 2 to index 5 (6 is not included).
   • The substring will be 'rin' (positions 2, 3, 4, 5).
   • Result: "rin"

2. s1 = slice(1, 5)

   • This will slice from index 1 to index 4 (5 is not included).
   • The substring will be 'trin' (positions 1, 2, 3, 4).
   • Result: "trin"

3. s1 = slice(1, 5, 2)

   • This will slice from index 1 to index 4, taking every 2nd character (1, 3).
   • The characters will be 't' from index 1 and 'i' from index 3.
   • Result: "ti"

4. s1 = slice(2, 6, 2)

   • This will slice from index 2 to index 5, taking every 2nd character.
   • The characters will be 'r' from index 2 and 'n' from index 4.
   • Result: "rn"

Putting this all together, the option that results in the string "ti" is:

s1 = slice(1, 5, 2)
