Step 3: This mode is called interactive mode as you can interact with IDLE directly, you type something (single unit in programming language) and press enter key Python will execute it, but you can not execute your entire program here. At command prompt type copyright and press enter key Python executes the copyright information.

Step 4:

Now Python is ready to read new command. Lets execute the following commands one by one.

Command -1 : print(“Prisoft Technology”)
Command -2 : primt(“Prisoft Technology”)

First command is correct and but second one has syntax error, here is the response from Python.
