So i took your advice and i am much closer. however, when i type in an invalid
address it loops back to the first prompt and asks you to enter your name: I
want it to ask you to re-enter your email address instead how would i go about
this?
Just move the line that asks for the name above the while loop.
Then it will only ask for the name once.
If you want to cater for multiple users each with multiple addresses then
you will need two nested loops.
while True
user = input(...name...):
collect other user data here
while True:
get/check addresses here
while cont:
name = input("Enter your name: ")
email1 = input("Enter your email address: ")
if not is_good_address(email1): continue
email2 = input("Enter an alternate email address: ")
if not is_good_address(email2): continue
phone = input("Enter your phone number: ")
contactlist = [email1, email2, phone]
emails[name] = contactlist
c = input("Enter another? [y]/n: ")
if c == 'n' or c == 'N':
cont = False
# Save data...
outfile = open("emails.dat", "wb")
pickle.dump(emails, outfile)
outfile.close
print("Your data has been saved to emails.dat")
def is_good_address(addr):
if '@' not in addr or '.' not in addr:
print('email needs @ and . at the same time')
return False
else:
return True
def open_existing_file():
# returns an empty dictionary or one that has data from a file
emails = {}
# Load the dictionary
try:
infile = open("emails.dat", "rb")
emails = pickle.load(infile)
infile.close()
except:
print("No file to open. Starting with no data.")
return emails
