These are the main types of sequence data types available in Python.
• String • List • Tuple

12.4.1 String
A string is a sequence data type in Python that stores a group of characters enclosed in single (' ') or double (" ") quotes.
A string in Python is an immutable sequence of characters enclosed in quotes. It is used to represent text such as
names, messages, sentences or any combination of letters, numbers and symbols.
Syntax of strings are as follows:

variable_name = "text"

# Assigning a string value to variable school
school = "Green Valley School"
# Printing the school name
print("School Name:", school)

12.4.2 List
A list is a sequence data type in Python that stores multiple values in an ordered manner. The elements of a list are
enclosed in square brackets [ ] and separated by commas. Each element has an index number starting from 0. A list
is mutable, which means its elements can be modified after it is created. Therefore, it is considered a dynamic data
structure because its contents can be changed.
Syntax of list is as follows:

list_name = [element1, element2, element3, ...]
