C:\AI\python\sample.txt In Chapter 1 we noted that the backslash character ‘\’ has special meaning in Python strings—namely that the next character should be interpreted in some special way. In order to get actual backslashes in a Python string we need to put a backslash before each of them. For example: filename = 'C:\\AI\\python\\sample ...

Sidebar: How Files Work Your computer uses file and folders to organize data content locally (on the hardware). A file is a single piece of content –a document, or a picture, or a song, or Python code. A folder is a structure that can hold 0+ files, as well as other folders. Folders can be nested for further organization.

Integer 5 is created in Python memory 2. Variable num is created, points to the memory location 3. num + 2 is evaluated; value 7 is created in memory 4. The name num is then attached to integer 7 in Python memory 5. 5 is no longer needed; gets freed up from memory int 5 int 7 >>> num = 5 num >>> num = num + 2

A variable is created the first time it appears on the left side of an assignment expression: x = 3 An object is deleted (by the garbage collector) once it becomes unreachable. Names in Python do not have an intrinsic type. Objects have types. Python determines the type of the reference automatically based on what data is assigned to it.

Python programs consist of statements that are translated by an interpreter or compiler into instructions that the CPU can execute ! We’ve discussed the Python programming language and its features: ! print() ! Data types: string, int, float ! Arithmetic operators ! Variables and variable naming convention !

print(f'{x:5.2f}\t\t{x*x:6.2f}\t\t{x*x*x:8.2f}') The output of this code snippet is this: This also demonstrates how the use of a value for width will enable the columns to line up. The following program demonstrates the use of strings, decimals, and floats, as well as tabs for a type of report that is often produced in a typical Python program.

Python is a strongly-typed and dynamically-typed language. Strongly-typed: Interpreter always “respects” the types of each variable.[1] Dynamically-typed: “A variable is simply a value bound to a name.” [1] Execution: Python is first interpreted into bytecode (.pyc) and then compiled by a VM implementation into machine instructions.

The example shows to use {:^} to center align the text. The number 10 is used to add 10 spaces to show the center-aligned when the value is replaced. Here, you can use 10 that will add 10 spaces in the nal text, and the value to be replaced will be center-aligned between the 10 spaces. The spaces of 10 are added just to show the

• Binding a variable in Python means setting a name to hold a reference to some object. • Assignment creates references, not copies • Names in Python do not have an intrinsic type. Objects have types. • Python determines the type of the reference automatically based on the data object assigned to it.

Python 3 and IDLE • We will use version 3.x of Python (where x is the most recent version • Differences between Python 2 and Python 3 are mostly minor, but can be confusing • Python comes with an IDE (Integrated Development Environment) called IDLE • IDLE is a REPL (Read-Evaluate-Print-Loop) that lets you enter Python statements one at a time, and see what they do
