One liner Python code is not easy:-
OSX 10.7.5, running python 3.4 inside a default bash terminal.
This is why I have switched to shell scripting...

Code:

  File "<stdin>", line 1
    x=0; while True: print(x)
             ^
SyntaxError: invalid syntax
>>> _

Notice the second attempt above as a 1 liner...
Yeah I know the assignment is not a statement, but neither are they in bash, but this is easy in the shell...
Miss out the assignment and put it on a separate line and it will run...

DESCRIPTION

   Traceback (most recent call last):
	      File "./scripts/osc-send", line 11, in <module>

	      import txosc # for __version__

       ImportError: No module named txosc

	osc-send --tcp --host=127.0.0.1 --port=17779 --type-tags=sif /ham/spam egg 2 3.14159

	osc-send -T -P 17779 /ham/spam egg 2 3.14159

OSC MESSAGES

       An OSC message consists of an OSC Address Pattern followed by an OSC Type Tag String followed by zero or more OSC Arguments.

OSC ADDRESSES

       An OSC Address Pattern is a string beginning with the character '/' (forward slash). It is mandatory to provide one.

OSC TYPE TAGS

       An OSC Type Tag String is a string (beginning with the character ',' (comma)) followed by a sequence of characters corresponding exactly to
       the sequence of OSC Arguments in the given message. Each character after the comma is called an OSC Type Tag and represents the type of the
       corresponding OSC Argument.

       Here is the list of supported type tags:

	   i - 32bit integer
	   h - 64bit integer
	   f - 32bit floating point number
	   d - 64bit (double) floating point number
	   s - string
	   S - symbol
	   c - char
	   m - 4 byte midi packet (8 digits hexadecimal)
	   T - TRUE
	   F - FALSE
	   N - NIL
	   I - INFINITUM

VALUES

       Values are space separated. Quoting strings might be handy.
