B. A substring will be sliced from index 0 through 5.
C. The substring will be sliced from index 3 through the end of the string, and then it will stride through the string.
D. A slice will be created using the characters before index 3 and then it will stride with the stride number 5.

1) len() would do the trick, but it's not a method of the String class, it's a function that returns the number of items in a container.
2) A. string_var[:6:2]
3) I'd expect to see the 4th and 5th characters of the string. Strings are zero indexed. None of the choices is correct.
4) A. The pop() function

Functions, methods are used in programming in other to make desired execution. The solution to the questions posed are given thus :

1.)

The len() function, counts the number of individual values in a string, list or table. Hence, the required function is len().

2.)

List slicing is used to select a certain portion of a string or table.

The required code will be string_var[:6:2]

  • This can be interpreted as everything before index 6 ; then take a stride of 2 though every other character in the slice.

3.)

string_var[3:5] ; Here, 3 represents the starting position, while 5 means up to but not including the index 5. Hence, the correct option is A.

4.)

The pop function is used to return an element from a particular list while also simultaneously deleting the element.
