Select all true statements about Python string indexing:
Python uses indexing operator (square brackets) to select a single character from a string
Python supports indexing in both left to right and right to left
Left to right indexing starts with 0
Right to left indexing starts with -1
The return type of a string index is also a string
Select all the ways you can extract "rocks" out of s = "Python rocks":
print(s[7:])
print(s[7:20])
print(s[-5:])
print(s[-5::1])
print(s[-5::])
Given the the string, py ="pythonic", select all the python constructs that give you the letter n:
print(py[6:5])
print(py[5:6])
print(py[-3])
print(py[5])
print(py[-3:-2])
Select what Python string method can be used to indicate whether a given string is a keyword in Python?
Note: below str represent a given string.
str.isupper()
str.isalnum()

Dear Student ,
As per the requirement submitted above , kindly find the below solution.
Question :
Answer :
Python uses indexing operator (square brackets) to select a single character from a string
Python supports indexing in both left to right and right to left
Left to right indexing starts with 0
Right to left indexing starts with -1
Explanation :All above statements in python are true.The return type of a string index is also a index number hence it is false.

Help C++ Write a string class. To avoid conflicts with other similarly named classes, we will call our version MyString. This object is designed to make working with sequences of characters a little more convenient and less error-prone than handling raw c-strings, (although it will be implemented as a c-string behind the scenes). The MyString class will handle constructing strings, reading/printing, and accessing characters. In addition, the MyString object will have the ability to make a full deep-copy of itself...
Python Programming: An individual playing card is represented as a string of two characters: • the first character is from "23456789TJQKA" and represents the rank, i.e., the number or value of the card. (Note that 10 is encoded as letter T to make all card ranks to be single letters) • the second character is from "cdhs" and represents the suit (clubs, diamonds, hearts and spades respectively). For example, "Jd" would be the jack of diamonds, and "4s" would be...
python Programming assignment: Let's think about doubly-linked lists. Define a class ListNode2, with three attributes: item, left, and rightL. Left link points to the previous node in the list, right link points to the next node in the list. You can also add the display method to this class (like we did it in class for the ListNode class). Then test your class. For example, create a linked list of 5 values: 34,1, 23, 7, and 10. Display it. Then...
