Introducing Python data containers
Python supports several data types, both numeric as well as collections. Defining numeric data types such as integers and floating-point numbers is based on assigning a value to a variable. The value we assign to a variable determines the type of the numeric data type. Note that a specific constructor (for example, int() and float()) can also be used to create a variable of a specific data type. Container data types can also be defined either by assigning values in an appropriate format or by using a specific constructor for each collection data type. We will study five different container data types in this section: strings, lists, tuples, dictionaries, and sets.
Strings
Strings are not directly a container data type. But it is important to discuss the string data type because of its wide use in Python programming and also the fact that the string data type is implemented using an immutable sequence of Unicode code points. The fact that it...
