In computer programming, a string is traditionally a sequence of characters,
either as a literal constant or as some kind of variable. The latter may
allow its elements to be mutated and the length changed, or it may be fixed
(after creation). A string is generally considered as a data type and is
often implemented as an array data structure of bytes (or words) that stores
a sequence of elements, typically characters, using some character encoding.
String may also denote more general arrays or other sequence (or list) data
types and structures.
Depending on the programming language and precise data type used, a variable
declared to be a string may either cause storage in memory to be statically
allocated for a predetermined maximum length or employ dynamic allocation to
allow it to hold a variable number of elements.
When a string appears literally in source code, it is known as a string
literal or an anonymous string.
In formal languages, which are used in mathematical logic and theoretical
computer science, a string is a finite sequence of symbols that are chosen
from a set called an alphabet.

The string type is used to store a sequence of characters (text). This is not
a built-in type, but it behaves like one in its most basic usage. String
values must be surrounded by double quotes

Everything is an Object in Python, hence even String is treated as an object in Python.
The sequence of characters is called String. A character can be anything like symbols, alphabets, numbers etc. The computer doesn’t understand any of these characters or Strings, rather it understands only binary numbers i.e. 0’s and 1’s.
We call this method as encoding and the reverse process is called decoding, and encoding is done based on the ASCII.
Declaring a String
Strings are declared using double quotes (“ “) or single quotes (‘ ‘).
