python maya opionVar

Set an optionVar

import maya.cmds as cmds

option_var_name = "myOptionVar"
option_var_value = 42

# Set the optionVar
cmds.optionVar(iv=(option_var_name, option_var_value))

Get the value of an optionVar:

import maya.cmds as cmds

option_var_name = "myOptionVar"

# Get the optionVar value
option_var_value = cmds.optionVar(q=option_var_name)
print(option_var_value)  # Output: 42

Check if an optionVar exists:

import maya.cmds as cmds

option_var_name = "myOptionVar"

# Check if the optionVar exists
if cmds.optionVar(exists=option_var_name):
    option_var_value = cmds.optionVar(q=option_var_name)
    print(option_var_value)
else:
    print("OptionVar does not exist.")

Delete an optionVar:

import maya.cmds as cmds

option_var_name = "myOptionVar"

# Delete the optionVar
if cmds.optionVar(exists=option_var_name):
    cmds.optionVar(remove=option_var_name)
    print("OptionVar deleted.")
else:
    print("OptionVar does not exist.")

String Array

import maya.cmds as cmds

def SetOptionVarStringArr(option_var_name, option_var_value):
    option_var_string = ",".join(option_var_value)
    cmds.optionVar(sv=(option_var_name, option_var_string))

def GetOptionVarStringArr(option_var_name):
    option_var_string = cmds.optionVar(q=option_var_name)
    option_var_value = option_var_string.split(",")
    return option_var_value
