Escaping a triple quoted string' newbie question

[Jules Stevenson]

Sorry, original post got a bit mangled, which didn't help the explanation at
all, reposted stuff:

Apologies if the terminology in this email is a little incorrect, I'm still
finding my feet.

I'm using python to generate some script for another language (MEL, in maya,
specifically expressions). Maya runs python too, but unfortunately its
expression language still has to use the maya syntax.

If I pass the expression this code (excuse the double spacing, email seems
to e ignoring my line breaks):

#runtime code [mel]
expRuntime="""
float $pos[]=particleShape1.worldPosition;

setAttr ("heartPP_1_"+particleShape1.particleId+".tx") $pos[0]; 

setAttr ("heartPP_1_"+particleShape1.particleId+".ty") $pos[1]; 

setAttr ("heartPP_1_"+particleShape1.particleId+".tz") $pos[2]; 
"""
dynExpression (p, s=expRuntime, rad=1)	#generate the expression

Then maya errors out, however if I pass maya an 'escaped' version:

expRuntime="""
float $pos[]=particleShape1.worldPosition;\nsetAttr
(\"heartPP_1_\"+particleShape1.particleId+\".tx\") $pos[0];\nsetAttr
(\"heartPP_1_\"+particleShape1.particleId+\".ty\") $pos[1];\nsetAttr
(\"heartPP_1_\"+particleShape1.particleId+\".tz\") $pos[2]; """

Then all is well. My question is, is there any way to convert the first
variable example to the second? It's a lot easier to type and on the eye.
