It will help later. To install Python, just run the installer. It will be installed in your “C” drive in a minute. Now you can go to “all programs” and run Python from there. Normally, a small IDE called IDLE comes with Python. You can write code and just run it. Let us see how it looks: 40 Chapter 7 ■ Python Environment Figure 7-2. Python IDE in Windows In the above image, you see on the top is IDLE, which is the Python Shell. You can directly get output from it. You can also go the file section of IDLE and create a new file.
Days print(lyrics) The output is like this:
8 days a week is not enough to love you. format(days)) The output:
8 days a week is not enough to love you.
What is the major difference between these two constructs? The difference is in the latest version of Python; we treat string as an object. Hence a “lyrics” object used a method called format() and passed a parameter that it wanted to format into it. ”), to call the method format() which is built-in in the string class.
Figure 5-3. Trying to read a non-text file with “cat” command In this part I want to show another trick that is often being used in Linux. Suppose you want to write a text file very quickly. You can use “nano”. It comes with every Linux distribution. Just type “nano” on your terminal and it will open up a text editor on the terminal itself. The next image shows you how it happens. 25 Chapter 5 ■ Linux Terminal, Basic Commands Figure 5-4. Nano text editor. How to save a file and exit the editor is written in it.
