Mel to Python conversion

[likage]

Hi all, I am trying to convert the following Mel into python but was met with some trouble.

Though I do not intend to implement the code, still, I would like to be enlighten, shedding some light as I am trying to learn / be knowledgeable in both Mel and Python..

The following is the Mel code:

string $window = `window -title "Long Name" -iconName "Short Name"`;
columnLayout -adjustableColumn true;


// this is maya's global variable of all the preset film backs
global string $gFilmbackTable[];


// create an option menu that will contain all the preset film backs
optionMenu - l "Film Gate" omFilmbackMenu;


// grab the film backs in the table and add them to the drop down menu
for($i=0; $i < size($gFilmbackTable); $i += 3) {
menuItem -l $gFilmbackTable[$i];
}

showWindow $window;

And the following is the converted Python that I did:

import maya.cmds as cmds
import maya.mel as mel


win = cmds.window(title = "Long Name", iconName = "Short Name", widthHeight = (200, 55))
cmds.columnLayout(adjustableColumn = True)


fbTable = mel.eval('global string $gFilmbackTable[]')
# fbValues = mel.eval('$gFilmbackTable')


cmds.optionMenu("omFilmbackMenu", label = "Film Gate")


cmds.showWindow(win)

First problem that I had, is grabbing the value of $gFilmbackTable. As I tried printing them out (fbValues), it either prompts me error saying - RuntimeError: Error occurred during execution of MEL script

Whereas in Mel tab, it is able to print out a list of things.. Guess I screwed up somewhere?

The second issue that I had would be converting the for statement (and onwards) in Mel to python. While I can think of replacing 'size' with 'len', but the other parameters within - $i=0 and $i += 3, how do I do so in Python?

[Kurian O.S]

import maya.cmds as cmds

import maya.mel as mel

win = cmds.window(title = "Long Name", iconName = "Short Name", widthHeight = (200, 55))

cmds.columnLayout(adjustableColumn = True)

fbTable = mel.eval('$tempFbValList = $gFilmbackTable')

print fbTable

cmds.optionMenu("omFilmbackMenu", label = "Film Gate")

# If you want all

#for eachItm in rfbTable:

#    cmds.menuItem(label=eachItm)

for eachItm in range(0, len(fbTable), 3):

    cmds.menuItem(label=eachItm)

cmds.showWindow(win)

You can use range to do the increment. And hope this helps
