Concatenate fields based on If/then statements

Question

Hello, I'm looking for some assistance writing a formula that concatenates addressing fields if they are not null. I have addresses broken out in individual text fields such as owner, address number1, address number 2, street direction, street name, street type, unit, city, and zip. All fields are text fields. In the address fields, not all values are populated. I only want values from fields that are populated. If you couldn't tell, I am not experienced with VB or python. My database has ~50000 records. I am using ArcMap 10.8. Is there any way populate a concatenated site address field from populated address fields? Example: OWNER SITUS_ADR1 SITUS_ST SITUS_ST1 SITUS_TYPE SITUS_CITY SITUS_ST SITUS_ZIP J AND J DOE 1234 S FIRST AVE PORT AB 99999 CONCATENATED SITUS= J AND J DOE, 1234 S FIRST AVE, PORT, AB, 99999 MR. ABC 1111 SEA DR PORT AB 99999 CONCATENATED SITUS= MR. ABC, 1111 FIRST AVE, PORT, AB, 99999 XYZ 2222 HWY Z PORT AB 99999 CONCATENATED SITUS= XYZ, HWY Z, PORT, AB, 99999

Yes, it's certainly possible, though I suggest you make the effort to learn Python (which is the easiest computer language to learn, ever).

Calculate Field field reference syntax is a bit more obtuse, so you want to follow the documentation carefully. That will result in a code block that looks like this:

def concatenateFields(f1,f2,f3,f4,f5,f6,f7):
    l = []
    if f1: l.append(f1)
    if f2: l.append(f2)
    if f3: l.append(f3)
    if f4: l.append(f4)
    if f5: l.append(f5)
    if f6: l.append(f6)
    if f7: l.append(f7)
    return ', '.join(l)

and an expression of:

concatenateFields(!SITUS_ADR1!,!SITUS_ST!,!SITUS_ST1!,!SITUS_TYPE!,!SITUS_CITY!,!SITUS_ST!,!SITUS_ZIP!)
