1. the entered email is a valid email address (email format is [USERNAME]@[ORGANIZATION].[DOMAIN]. i.e. it should have '@' followed by organization name then at least one '.'and domain)
2. determine if the entered email is a KFUPM email or not (KFUPM emails ends with @kfupm.edu.sa)
3. if the entered email is a valid KFUPM email, determine if it is a freshman student email or not (assume all freshman students have ID numbers starts with s2019 and the student ID length is 9 digits)

Sample run	Sample run	Sample run
write your email address: [email protected] The email address is Valid The entered email is a KFUPM email The entered email is a freshman student email	write your email address: ics@104. The entered email is not valid	write your email address: [email protected] The email address is Valid

Answer 1

Python program :

#asking user to enter email
email=input("write your email address:")
#checking if email contains @
if(email.find("@")!=-1 and email.find(".")!=-1):
    #if email is valid
    #checking if email contains some domain name
    emailList=email.split(".") #split email based on .
    if(len(emailList)>1 and emailList[1]!=''):#when length of emailList is greater than 2
        #means email contains domain name
        print("The email address is Valid")
        #checking for KFUPM
        if(emailList[0].split("@")[1].upper()=="KFUPM"):
            #when email is KFUPM email
            print("The entered email is a KFUPM email")
            #checking for whether freshman email
            userName=emailList[0].split("@")[0]
            if userName.startswith('s')==True:
                #when email id starts with s then checking for length of email
                #spliting into characters
                idList=list(emailList[0].split("@")[0])
                #declaring variable for digitCount
                digitCount=0
                #using for loop
                for i in range(1,len(idList)):
                    if(idList[i].isdigit()):
                        #when idList is digit then
                        digitCount=digitCount+1 #increment digit count
                if digitCount==9: #when digitCoutn is 9 then
                    print("The entered email is a freshman student email")
        else:#when email does not contains KFUPM
            print("The entered email is a valid email")
    else:#when email contains . but not contains domain name
        print(email + " is not valid")
else: #if email does not contains  @
    print(email+" is not valid")
