Need help with "IndentationError: expected an indented block"

[Pranav]

There is no indent space between the function declaration and body.


It should be like this.

def print2Smallest(arr):
 
	arr_size = len(arr)
	if arr_size < 2:
		print "invalid output"
		return

Text editors like Notepad++ have the option of indenting the lines of code.
Select the text within the function body and use indent option.
