I have a number of columns in a number of tables withinh a FGDB where I need to extract the unique values for each column. 

For Example: the values may be [1,2,2,2,3,4], and I am trying to return [1,2,3,4]

I could do this job a number of other ways in ARCGIS but I am trying to extend myself.

I have found a piece of python on the web that I think will do the job but I am struggling to get it to run (I keep getting an invalid syntax error as I keep getting the syntax error in line 3) this will no doubt be a really simple user error. 

Code Snippet below

```
import arcpy

def unique_values(r'N:\GISProjects\Landuse\Plant_Biosecurity_Project\ArcGIS_Online.gdb\Holdings_Property_Merge' , 'LU_ALUMMaj'):
with arcpy.da.SearchCursor(table, [field]) as cursor:
    return sorted({row[0] for row in cursor})

```

This is the Error Message I get from sublime text:

```
 File "C:\Users\hawkinle\Desktop\STDTAS\Unique_Data.py", line 3
def unique_values(r'N:\GISProjects\Steve_Eastwood_Landuse\Plant_Biosecurity_Project\ArcGIS_Online.gdb\Holdings_Property_Merge' , 'LU_ALUMMaj'):
                                                                                                                             ^
SyntaxError: invalid syntax

```

**Updates from Original Question**

I have now updated my code with the answer provided by below but am recieving a secondary error.

**New Code Snippet:**

```
import arcpy

def unique_values(table , field):
    with arcpy.da.SearchCursor(table, [field]) as cursor:
        return sorted({row[0] for row in cursor})

myValues = unique_values(r'N:\\GISProjects\\Landuse\\Plant_Biosecurity_Project\\ArcGIS_Online.gdb\\Holdings_Property_Merge' , 'LU_ALUMMaj')

print (myValues)

```

I am getting a new error message related to a runtime error 

```
Traceback (most recent call last):

```

I assume from the reading I have done that this relates to setting the env.workspace ?
