USING ESCAPE SEQUENCES WITH STRINGS
An escape character or escape sequence is a character followed by a backslash (\). Escape

sequences allow you to include special characters such as a backslash (\) or quotes in strings. To
do this, simply add a backslash (\) before the character
you want to escape.
If you add any special character, such as an apostrophe,

greeting = "It\'s a beautiful day!"
print(greeting)

Similarly, you can include a new line (\n), a horizontal tab (\t) and a backspace (\b).

ACCESSING CHARACTERS OF A STRING

In Python, each character in a string has a position called an index. Indexing starts from 0
(positive indexing) for the first character and -1 (negative indexing) for the last character. You
can access and process an individual character or a set of characters from a string also known

as Traversing.
There are two ways of indexing a string:

Positive indexing: Indexing starts from the left, with the first character at index 0.

Negative indexing: Indexing starts from the right, with the last character at index -1.
