Wow. Yes that code could be improved, a lot. def means declare function. Simply put, it basically creates a variable that, when called, will execute instructions.

PHP Code


<?php 
def hi():  #Creates a function under the name "hi"
  print "Hello World"  #This is where the body of the functin is (the instructions executed)
hi()  #This is the function call, and when this is called, all the instructions within the function body will be executed successively 


The body of the function is not executed until the function is called.

You can read more about functions here:

Ah, that's quite easy to understand. And how can I improve the code?

Also, when writing out the body of the def how do you tell python this is the end of the body of def?

The body of the function is indented. Once indentation ceases, the interpreter assumes that that is the end of the function declaration.
