I`m trying to select many values from the parameter "Estado" which will be use in the query in the code. This parameter has a value list, string type.

I think it`s a format() problem...But also I will have problems to put in the SQL expression format: 'VALUE1','VALUE2'.

I tried with .split(';'), but do not work.

import arcpy

Layer1 = arcpy.GetParameterAsText(0) 
Tabela1 = arcpy.GetParameterAsText(1) 
Estado = arcpy.GetParameterAsText(2).split(';') 
Ano = arcpy.GetParameterAsText(3).split(';')  
mxd = arcpy.mapping.MapDocument("CURRENT")  
Saida = arcpy.GetParameterAsText(4)
stats = []

for lyr in arcpy.mapping.ListLayers(mxd):   
    lyr.name = Layer1
    lyr.definitionQuery = """UF IN ({})""".format(Estado)

for field in arcpy.ListFields(Tabela1):
    if field.name in (Ano):
        stats.append([field.name, "SUM"])

arcpy.Statistics_analysis(Layer1, Saida, stats, "")        

When I tried to run the script, I got this error:

Traceback (most recent call last):
  File "F:\AgroBD.gdb\M6a.py", line 19, in <module>
    arcpy.Statistics_analysis(Layer1, Saida, stats, "")

Python's split method turns a string into an array for your variable Estado.

When you call String.format in python, it simply uses the built-in array to string conversion, which formats Estado as [u'AC', u'AM']. The square brackets and the u character are likely what's causing you problems.

Instead of relying on python's built-in array to string conversion (implicitly called by format()), you should use join() to control how the string is created.
