Unhappy how to pass arguments to maya.mel.eval()

userSetup.py file takes precedence over userSetup.mel
so, i wanted to add some paths to "MAYA_SCRIPT_PATH" via python
this example for getting variables works fine

import maya.mel as mel
import os.path
import maya.cmds as cmds
def printMayaPaths():
	msp = mel.eval('getenv MAYA_SCRIPT_PATH')
	msp = str(msp)
	myList = msp.split(';')
	for each in myList:
		print each


but this one gives error
def addFolderToMayaPath(p):
	msp = mel.eval('getenv MAYA_SCRIPT_PATH')
	msp = str(msp)
	myList = msp.split(';')
	msp += ";" + p
	type(msp)
	mel.eval('putenv "MAYA_SCRIPT_PATH" ' + msp)
	maya.cmds.rehash()


QUESTION:
how exactly to add python list or path to MAYA_SCRIPT_PATH via python
huge thanks in advance everyone for time and suggestions and solutions
regards,lala

In Python you can use the os module to access environment variables. They are stored in the environ dictionary:

import os

pathsep = os.pathsep
my_script_dir = "C:/my_scripts_dir"
os.environ["MAYA_SCRIPT_PATH"] = "{0}{1}{2}".format(my_script_dir, 
                                                                                          pathsep, 
                                                                                           os.environ["MAYA_SCRIPT_PATH"])
