Then keep reading… Below are 15 free Python eBooks, plus a couple extra, that you can take with you anywhere. This report guides you through the implicit decision tree of choosing what Python version, implementation, and distribution is best suited for you. It weighs and discusses the merits of each of these choices, and briefly discusses the reasons each option exists. This report provides a brief yet comprehensive introduction to Python for engineers, researchers, and data scientists who are already familiar with another programming language.
[Read PDF] Learn Python in One Day and Learn It Well: Python for Beginners with Hands-on Project.
If you are an absolute beginner in Programming, you'll find that this book explains complex concepts in an easy to understand manner. Examples are carefully chosen to demonstrate each concept so that you can gain a deeper understand of the language. If you are an experienced coder, this book gives you a good base from which to explore Python.
The appendices at the end of the book will also provide you with a convenient reference for some of the commonly used functions in Python. In addition, as Richard Branson puts it: "The best way of learning about anything is by doing". At the end of the course, you'll be guided through a project that gives you a chance to put what you've learned to use. Table of Contents Chapter 1: Python, what Python?
What is Python? Why Learn Python? Welcome to the exciting world of programming. I'm so glad you picked up this book and I sincerely hope this book can help you master the Python language and experience the exhilaration of programming.
Before we dive into the nuts and bolts of Python programming, let us first answer a few questions. Python is a widely used high-level programming language created by Guido van Rossum in the late s. The language places strong emphasis on code readability and simplicity, making it possible for programmers to develop applications rapidly. Like all high level programming languages, Python code resembles the English language which computers are unable to understand.
We'll look at how to install the Python interpreter in Chapter 2. There are also a number of third-party tools, such as Py2exe or Pyinstaller that allow us to package our Python code into stand-alone executable programs for some of the most popular operating systems like Windows and Mac OS. This allows us to distribute our Python programs without requiring the users to install the Python interpreter. The good news is all high level programming languages are very similar to one another.
What differs is mainly the syntax, the libraries available and the way we access those libraries. A library is simply a collection of resources and pre-written codes that we can use when we write our programs. If you learn one language well, you can easily learn a new language in a fraction of the time it took you to learn the first language.
If you are new to programming, Python is a great place to start. One of the key features of Python is its simplicity, making it the ideal language for beginners to learn. Most programs in Python require considerably fewer lines of code to perform the same task compared to other languages such as C.
This leads to fewer programming errors and reduces the development time needed. In addition, Python comes with an extensive collection of third party resources that extend the capabilities of the language. As such, Python can be used for a large variety of tasks, such as for desktop applications, database applications, network programming, game programming and even mobile development.
Last but not least, Python is a cross platform language, which means that code written for one operating system, such as Windows, will work well on Mac OS or Linux without making any changes to the Python code. Convinced that Python is THE language to learn? Chapter 2: Getting ready for Python Installing the Interpreter Before we can write our first Python program, we have to download the appropriate interpreter for our computers.
However, note that Python 2 is currently still rather widely used. Hence if you learn Python 3, you will likely have no problems understanding codes written in Python 2. The correct version should be indicated at the top of the webpage. Click on the version for Python 3 and the software will start downloading. Click on the release version that you want. The installer to use depends on two factors: 1. The processor bit vs bit that you are using.
For instance, if you are using a bit Windows computer, you will likely be using the "Windows x MSI installer". Just click on the link to download it. If you download and run the wrong installer, no worries. You will get an error message and the interpreter will not install.
Simply download the correct installer and you are good to go. Once you have successfully installed the interpreter, you are ready to start coding in Python. You launch the IDLE program like how you launch any other programs. The Python Shell allows us to use Python in interactive mode. This means we can enter one command at a time. The Shell waits for a command from the user, executes it and returns the result of the execution.
After this, the Shell waits for the next command. Try typing the following into the Shell. Hence, the Shell returns the answer 5. The Shell replies True. Finally, print is a command asking the Shell to display the line Hello World. The Python Shell is a very convenient tool for testing Python commands, especially when we are first getting started with the language. However, if you exit from the Python Shell and enter it again, all the commands you type will be gone. In addition, you cannot use the Python Shell to create an actual program.
To code an actual program, you need to write your code in a text file and save it with a. This file is known as a Python script. Type the following code into the text editor not the Shell. It is a comment written to make our code more readable for other programmers. This line is ignored by the Python interpreter. Make sure you save it with the. You have just successfully written your first Python program. You should see the words Hello World printed on your Python Shell. However, note that he used Python 2 in the video, so some commands will give you an error.
What are variables? Variables are names given to data that we need to store and manipulate in our programs. For instance, suppose your program needs to store the age of a user. To do that, we can name this data userAge and define the variable userAge using the following statement. You can then access and modify this data by referring to it by its name, userAge. Every time you declare a new variable, you need to give it an initial value. In this example, we gave it the value 0. We can always change this value in our program later.
We can also define multiple variables at one go. However, the first character cannot be a number. In addition, there are some reserved words that you cannot use as a variable name because they already have preassigned meanings in Python. These reserved words include words like print, input, if, while etc. Finally, variable names are case sensitive. There are two conventions when naming a variable in Python. We can either use the camel case notation or use underscores.
Camel case is the practice of writing compound words with mixed casing e. An example will likely clear this up. Type the following code into your IDLE editor and save it. However, this is not so in programming. Run the second program. Basic Operators Besides assigning a variable an initial value, we can also perform the usual mathematical operations on variables.
Suppose we have the variable x, with an initial value of The same works for all the 7 operators mentioned in the section above. Integers Integers are numbers with no decimal parts, such as -5, -4, -3, 0, 5, 7 etc.

Глушитель кашлянул, Беккер плашмя упал на пол.
Черт возьми, - подумала Сьюзан. - Почему же так долго. - Ты явно не в себе, - как ни в чем не бывало сказал Хейл. - Какие-нибудь проблемы с диагностикой. - Ничего серьезного, - ответила Сьюзан, хотя вовсе не была в этом уверена.
- Я опытный диагност. К тому же умираю от любопытства узнать, какая диагностика могла заставить Сьюзан Флетчер выйти на работу в субботний день. Сьюзан почувствовала прилив адреналина и бросила взгляд на Следопыта. Она понимала, что не может допустить, чтобы Хейл его увидел, - последует слишком много вопросов. - Я хочу сохранить это в тайне, - сказала .
