For 1, 2, and 3, the console of other OSes may do as well or better than Idle. Whenever you hear REPL think of an environment which allows you quickly test code snippets and see results immediately, just like a Calculator.
In Python shell, enter the following calculations one by one and hit enter to get the result. Try it now. In our case, the print function prints the argument i. A string is just a sequence of string enclosed inside single or double quotes. For example: "olleh" , 'print it' are strings but 1 and 3 are not. Don't worry, we are not expecting you understand these things at this point.
In upcoming lessons we will discuss these concepts in great detail. A statement is simply a instruction for the Python interpreter to execute. Statements are of different types as we will see.
A program usually consists of sequence of statements. Python Shell is great for testing small chunks of code but there is one problem - the statements you enter in the Python shell are not saved anywhere. In case, you want to execute same set of statements multiple times you would be better off to save the entire code in a file. Then, use the Python interpreter in script mode to execute the code from a file.
Create a new directory named python , you can create this directory anywhere you want, just remember the location because we will use this directory to store all our programs throughout this course.
Create another directory inside python named Chapter to store the source files for this chapter. To create programs you can use any text editor, just make sure to save your file as plain text. However, if you are desperately looking for recommendation go for Sublime Text.
Create a new file named hello. By convention, all Python programs have. The file hello. To execute the program, open terminal or command prompt and change your current working directory to python using the cd command, then type the following command:. This command starts the Python interpreter in script mode and executes the statements in the hello.
We know that in the Python Shell, if you type any expression and hit enter, the Python interpreter evaluates the expression and displays the result. However, if you type these statements in a file and run the file, you will get no output at all. Warning: On the Python homepage, the latest version available for download is actually 3. Do not install this! This version is not backwards compatible with the code that you'll be writing in this course for example, you have to type print "test" instead of print "test".
Instead, be sure to download the version listed above. IDLE is the standard Python development environment. Its name is an acronym of " I ntegrated D eve L opment E nvironment".
It works well on both Unix and Windows platforms. It has a Python shell window, which gives you access to the Python interactive mode. It also has a file editor that lets you create and edit existing Python source files. Whenever you enter a complete code fragment, it will be executed.
