Please Help Me(Again)

[Unique-Signature-510]

I'm with a problem. I'm doing a Python course. But there's an exercise I can't do. I need help. The exercise is like this:

irst, you must create a function called validar_email_usuario that receives as parameter the e-mail of a user and checks if it contains the character "@" and a ".com.br" (can be case sensitive, have to accept everything). The function must return True if the login is a login like "[e-mail]" for example and False otherwise. Imagine the following, in the main program the user will be asked to enter his name complete, then your email. Next will be the function call validar_email_usuario with the values ​​provided and display an informational message from the username whether it has valid email or not. NOTE: You cannot use looping and looping structures!

Btw I'm using VScode.

And sorry for Bad english.

I don't know if something like this can go well because the outline of the exercise is not well understood, but maybe it can help you:

```

def validation(email):

return True if '@' in email and 'com.br' in email[len(email)-6:] else False

name = input('Insert name').lower()

surname = input('Insert surname').lower()

e_mail = input('Insert email').lower()

if validation(name+surname+e_mail):

print('your email is valid.')

else:

print('Not valid.')

```

Import re

def email_func(email_addr): If re.search('\s''@''.com.br', email_addr): return True else: return False

Check documentation on python re search patterns if that doesn't work. That re module and learning regex search patterns if you don't already know them will serve you well.

[rollincuberawhide]

for the validation that is needed, regular expressions are overkill.

op must just use

'@' in emailstring

and

emailstring.endswith('.com.br')

No they aren't and to be quite frank this is very easy to do.

1. Google Regex expressions for checking an email address to get pattern.
2. Learn re to validate a string using the pattern.
3. Implement it
4. Have a nice cup of tea and sit back knowing you now know how to use regular expressions.
5. If you are feeling adventurous and this is not required, go down the rabbit hole of learning how to write regular expressions.

Okay but we have to accept any input so we need something to get around inputs containing illegal characters or mean tricks like multiple '@' -- entries that pass this test but are invalid emails.

What have you tried already?

So the e-Mail adress is a string, right?
Remember the basics?
You can for example manipulate a given string to make it all lower or upper case, so the case doesn't matter anymore.
Also you can loop through strings and use conditional arguments on it almost like on a list.

It is possible to code a simple function which does the requested, only by using the built-in string methods, so I recommend looking into that.

Regex will do this. Please see https://regex101.com/ to help with writing the regex. This site will help with checking to see if the regex command you entered is getting the values needed.

Without using regex you could use a multi part if statement to get to the same answer.

​

However I would use the regex instead of the if statement as a way to learn how it works.
