Hello All,
I have a python assignment. I have to make sure that when user inputs email
that the program verifies that the address as a @ and a “.” in the entry or
else return an invalid email error.
A Very rudimentary form of email validation. i cannot get the program to work.
Here is what i have so far:
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 :")
email2 = input("Enter alternate email address :")
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
def email1():
if '@' not in email and '.' not in email:
print('email needs @ and . at the same time')
# Save data...
outfile = open("emails.dat","wb")
pickle.dump(emails,outfile)
outfile.close
print("Your data has been saved to emails.dat")
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()
Here is the error message :
/Library/Frameworks/Python.framework/Versions/3.4/bin/python3.4
/Users/stephaniequiles/Downloads/emailsupdate.py
Traceback (most recent call last):
File "/Users/stephaniequiles/Downloads/emailsupdate.py", line 42, in <module>
main()
File "/Users/stephaniequiles/Downloads/emailsupdate.py", line 6, in main
emails = open_existing_file()
UnboundLocalError: local variable 'open_existing_file' referenced before
assignment
Process finished with exit code 1
not sure why it is not recognizing that the open_existing_file() function needs
to be returned to the “emails” variable? I am guessing it has to do with my
syntax? any suggestions, please?
Thank you
Stephanie Quiles
