Pass buffer as variable using arcpy.Buffer_analysis

[المشرف العام]

I am trying to pass a buffer variable and seem to have run into some sort of limitation of the command.

The buffer will vary each time the script is run so I need to have this parameter variable

varBuffer = 5 # in this instance varBufffer = '"'+ varQuan + ' Miles"' I tried this but it does not work:

arcpy.Buffer_analysis(projectArea, MileBuff_shp, varBuffer, "FULL", "ROUND", "ALL", "") Only this works.

arcpy.Buffer_analysis(projectArea, MileBuff_shp, "5 Miles", "FULL", "ROUND", "ALL", "") Is there a work around for this?
