I'm trying to reclass values in field calculator using Python.

I want any value >= '5' to remain the same (return same value). Anything else to be = '0'.

Yes, DIST_EDGE are numbers.

I'm getting an invalid syntax error in Line 1 (see below)

Here's what I came up with (new script following comments):

    Is the data type for DIST_EDGE string or numeric? String values are accessed with quotes, numbers are not. – phloem Jan 7 '15 at 17:06
  • Once you call the function Reclass(!POINTS_Adelard.DIST_EDGE!), the passed value is stored in a variable, no '!'. I've updated my answer below. – phloem Jan 7 '15 at 18:37

Assuming the data type for DIST_EDGE is numeric, the function should be (note, no quotes):

def Reclass(dist):
    if dist >= 5:
        return dist
        return 0

However, if DIST_EDGE is a string data type, you must cast it to a number before making your comparison:

def Reclass(dist):
    if int(dist) >= 5:
        return dist
        return '0'

    These functions will work. The actual problem with the OP's code is that his function is using !POINTS_Adelard.DIST_EDGE! as a parameter name, which is of course invalid Python syntax. Replacing those references in the function (but not the final function call) with dist (as in @phloem's examples) will resolve this. – nmpeterson Jan 7 '15 at 18:57
