Hi Joe, before testing your code, I agree with you, the code is best run
in MEL before you even brought up that concern I was thinking, it
doesn't make sense, and if someone in the group brought it to the
surface, it wouldn't surprise me.
The reason; the MEL code has to be wrapped in python code, otherwise the
other script, did I mention it was part of another script, regardless if
I did or didn't, it can't read MEL individually, that is why, not I
wanted to, or felt the desire to ;-) instead I had to wrap it in python.
;-)
Let me give your code a run ;-)

Questioning the code aside:
The immediate issue you're running into seems to be that Python
doesn't support multi-line strings which are just denoted with a
single quotation mark.
If you're going for multi-line strings, you'll need to use the
multi-line string quote-- """String here""" -- Note the triple quotations.
With that said, I agree with Marcus here.
First, why are we calling this script from Python? It seems like it
might be better suited to be entirely in MEL. I've run into a number
of situations where I need to call MEL code from my Python scripts,
but this looks like primarily coding in MEL and then forcing it into
Python.
You could do the same thing more like this:
# Avoid importing under other names
import maya.mel as mel
uMin = -1
uMax = 1
vMin = -1
vMax = 1
for i in range(uMin, uMax - uMin):
for j in range(uMin, uMax - uMin):
path = r"c:\\5\\uvImage_u{0}_v{1}.jpg".format(i+1, j+1)
UVCmd = r'uvSnapshot -o -aa -uMin {0} -uMax {1} - vMin {2}
-vMax {3} -n "{4}" -xr 4096 -yr 4096 -ff jpg;'
UVCmd = UVCmd.format(i, i+1, j, j+1, path)
mel.eval(UVCmd)
It's best if you're going to use Python to use it all the way through,
with independent MEL commands where there is no other option (which,
to be fair, happens all too often in Maya).
Let me know if you have questions on that code, I utilized a few
string formatters that I find make my code easier to read, but can be
a bit confusing if you're not used to them.
Hope that helps!

Please paste an example of your actual code. A big pink long
probably means you have a python syntax error. The Mel code
should be in an actual string so it should syntax highlight like
a string.

The beginning and end of the MEL string has a nice long pink
line in Sublime, I assume this is because Sublime doesn't
have syntax highlighting for MEL ?
The MEL code doesn't execute, I get a SyntaxError on line 1:
EOL while scanning string literal ?

Alright;

Correct ?
Yep. Where <MEL script> is a string.
Converters are fine for some, I rather understand the
guts :)

Hi, I have a script that uses the def() syntax,
the problem is the original code is MEL, using
the following syntax is not working ?
def acme()
[MEL code]
