I'm trying to use the field calculator to poplulate a string field in a table based on info in another string field. This is what I have:
def Reclass(Correction_Comments):
if (MSAGSTREETNAME) = 'HEMLOCK':
return 'IN PARCEL 103'
In the call box:
Reclass( !Correction_Comments!)
I keep getting a parsing error. What's wrong?

The parameter "Correction_Comments" from your function is not used at all within the function. Instead, there is a variable "MSAGSTREETNAME", a local variable that is not referenced elsewhere. In addition, the if statement is using an assignment (=) rather than a test (==).
Modifications:
def Reclass(streetnamefield):
if streetnamefield == 'HEMLOCK':
return 'IN PARCEL 103'
Reclass( !Correction_Comments!)
This will pass the field Correction_Comments into your Reclass function. You may instead want to run this in the Field Calculator for the Correction_Comments field, against the MGAGSTREETNAME field e.g. right click Correction_Comments, Field Calculator, and run with Reclass(!MGAGSTREETNAME!).
