Zylabs still didn't like that answer. This is what I finally came up with that worked.
strInput=""
#Loop for multiple lines
while(strInput!="q"):
#User input
strInput = input('Enter input string:\n')
#Check for comma(,)
if"," in strInput:
#String parsing
words = strInput.split(",")
FW = words[0].split()
SW = words[1].split()
print("First word:",FW[0])
print("Second word:",SW[0])
print("")
#Check for q
elif(strInput=="q"):
break
#If comma(,) is not present
else:
print("Error: No comma in string.\n")
