Batch and Mass Exporting ArcGIS MXD to PDF using ArcPy

Here is the code if someone need this, 

import arcpy, sys, os, string

mxdList = string.split(arcpy.GetParameterAsText(0), ";")
outloc = arcpy.GetParameterAsText(1)
resolution = arcpy.GetParameterAsText(2)
georef_info_option = arcpy.GetParameterAsText(3)
layers_attributes_option = arcpy.GetParameterAsText(4)

for item in mxdList:
    item = item.strip('\'')
    mxd = arcpy.mapping.MapDocument(item)
    base = os.path.basename(item)
    base = os.path.splitext(base)[0] + ".pdf"
    pdf_path = os.path.join(outloc, base)

    # Switch to layout view
    for df in arcpy.mapping.ListDataFrames(mxd):
        if df.name == "Layers":
            mxd.activeView = df.name
            mxd.title = df.name

    # Export to PDF with specified parameters
    arcpy.mapping.ExportToPDF(mxd, pdf_path, resolution=resolution, georef_info=georef_info_option, layers_attributes=layers_attributes_option)
    
    arcpy.AddMessage(base + " has been exported to PDF")

and  here is how to implement it in ArcGIS Desktop
