and the pointer “ptr” stores the address of the variable x. The & (addressof) operator is used to obtain the memory address of the variable x. A pointer can also be declared and initialized in a single step. It is called the pointer definition. ...
This chapter begins our tour of the Python language. In an informal sense, in Python, we do things with stuff. “Things” take the form of operations like addition and concatenation, and “stuff” refers to the objects on which we perform those operations. In this part of the book, our...

For computers, each data type can be thought of as being quite different, like words and numbers, so we will have to be careful about how we use them to assign values and how we manipulate them through operations.Numbers Any number you enter in Python will be interpreted as a number; yo...
Understanding the data types in Python is essential for writing efficient programs. Data types determine the type of value a variable can store, including a number, text, or lists. They help organize and process data effectively. They also ensure that the operations are performed correctly. In ...
Python x =Trueprint(type(x))# outputs: <class 'bool'> Internally,boolis treated as a special type of integer. Technically,Truehas a value of 1 andFalsehas a value of 0. Typically, Booleans aren't used to perform mathematical operations; rather, they're used to make decisions and perfo...
