arcgis desktop - Field Calculator: Split address into house number, street name

I have an ADDRESS field in a table with values like:

• 1 MAIN ST


• 20 SIDE AVE W


• 300 JOHN DOE JR RD S

I want to use the field calculator to split the addresses and insert the parts into HOUSE_NUMBER and STREET_NAME fields. Example:

• 300 into HOUSE_NUMBER


• JOHN DOE JR RD S into STREET_NAME

I also want the tool to check if the value that will be put into HOUSE_NUMBER is a valid integer (and ignore it if it isn't).

How can I do this?

Answer

This python script seems to do the trick. It allows the user to choose whether to return the house number or the street name to the field (by commenting-out the non-applicable ReturnType line).

def addressParser(inString):
    returnType = "House Number"
    #returnType = "Street Name"

    splitString = inString.split(' ',1)
    houseNumber = splitString[0]
    streetName = splitString[1]


    if returnType == "House Number":
        if houseNumber.isdigit():
            return houseNumber
        else:
            return
    if returnType == "Street Name":
        return streetName
    else:
        return
