do we yield two separate values, or a tuple?

In python you can return/yield only a single object, that can be a tuple of values. (If there is a comma it'a a tuple.)

The description should describe the task.

True if n > 0 else False is an unnecessarily complicated version of n > 0.

For consistency, if you wrap a bool expression, you should wrap all expressions:
True if n > 0 else False -> True if (True if n > 0 else False) else False -> ...

And why not (1 if n == 1 else n) > 0 or True if (True if (0 if n == 0 else 1 if n == 1 else n) > 0 else False) else False?

How to add random tests

Why is if-else so bad

• No sample tests
• No random tests
• Using if-else to solve this kata is very bad practice

fixed

It is hardly worth calling this pattern an email address. Real world email addresses are so much more complex, and are so much harder to validate. ALL your rules are actually wrong.

• an addres does not need to have a domain part, so addresses without @ are completely valid. there are also situations where more than one @ is valid.
• some special characters are, possibly conditional, valid in the local part of an email address. +, . and even ( space ) are valid.
• subdomains exist. also, especially with new TLDs, domains without .s exist.
• a . at the end of the domain is valid ( which has a meaning to DNS )
• some special characters are also valid in the domain part of the address.

If it's worth doing, it's worth doing well. Don't call this email validation.

• Missing describe/it blocks in both sample and full tests.
• Missing from solution import isemail in both sample and full tests.
• There should be tests with underscores in domain.
• Duplicate?

Random and sample tests added

Okay I wrote my own description and I think that it should be fine

Hi I am new here and I am still trying too figure out how to write test but I think that I will add them soon
thank you for your comment
