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?
Here is the corrected code :
import pickle
def main():
cont = True
emails = open_existing_file()
print(emails)
# Get data...
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
main()
Thanks
