string = input()

def check(stirng): // cheking string having "," or not .

if string.find(","):

print(string)

print("Error:no comma in string")

def saperate(string):

a= string.split(",") // it return a list of word saperate with comma

print(string)

print("First Word:"+a[0])

print("Second Word:"a[1])

def loop():

while ( stirng == "q"): //its loop the string while the input string not equal to "q",

return saperate(string)

2.13 LAB: Warm up: Parsing strings (1) Prompt the user for a string that contains two strings separated by a comma. (1 pt) Examples of strings that can be accepted: Jill, Allen Jill, Allen o Jill Allen . Ex: Enter input string: Jill, Allen (2) Report an error if the input string does not contain a comma. Continue to prompt until a valid string is entered. Note: If the input contains a comma, then assume that the input also contains two strings (2 pts) Ex: Enter input string: Jill Allen Error: No comma in string. Enter input string: Jill, Allen (3) Using string splitting, extract the two words from the input string and then remove any spaces. Output the two words. (2 pts) Ex: Enter input string: Jill, Allen First word: Jill Second word: Allen (4) Using a loop, extend the program to handle multiple lines of input. Continue until the user enters q to quit.
