![]() ![]() The question is, do I have to compile my Python scripts to make them faster or how can I compile them? The answer is easy: normally, you don't need to do anything and you shouldn't bother, because "Python" is already doing the thinking for you, i.e. There is even a way of translating Python programs into Java byte code for the Java Virtual Machine (JVM). This is a similar approach to the one taken by Java. Python code is translated into intermediate code, which has to be executed by a virtual machine, known as the PVM, the Python Virtual Machine. (At the end of this chapter, you will find the definitions for Compilers and Interpreters, in case you are not already familiar with the concepts!) People would assume that the compiler translates the Python code into machine language. But calling Python a compiled language would be misleading. The truth is: Python is both an interpreted and a compiled language. Most probably you have read somewhere that the Python language is an interpreted programming or a script language. So, after you have found the editor or the IDE of your choice, you are ready to develop your mini program, i.e.Įnjoying this page? We offer live Python training courses covering the content of this site.Įnrol here Starting a Python Script under Windows Python Internals Of course, you can also use an IDE (Integrated Development Environment) like P圜harm or Spyder for this purpose. The Emacs works for Windows as well, but Notepad++ may be the better choice in many cases. For Linux you can use vi, vim, emacs, geany, gedit and umpteen others. There are lots of editors, but you should choose one, which supports syntax highlighting and indentation. To save and edit our program in a file we need an editor. We have to include our print function into a file. We will use a slight variation of the "Hello World" theme. Some may like to call such a little program "script". This way, we can use a program over and over again without having to type it in again. Type "help", "copyright", "credits" or "license" for more information.īut, as we said at the beginning, we want to write a "serious" program now, i.e. It might be necessary to use "python3" to get a Python3 shell: $ python3 We start a Python interactive shell in a terminal with the command "python". ![]() a program which prints the string "Hello World". You will hardly find any beginner's textbook on programming, which doesn't start with the "almost mandatory" "Hello World" program, i.e. ![]() We want to write now our first serious Python program. So far we have played around with Python commands in the Python shell. ![]()
