Suppose i have a function like this below:
def set_identity_key(
key: str
email: str | None = None,
phone: str | None = None,
) -> None:
data = {
"email": email,
"phone": phone,
}
set_key(
key=key,
value=data,
)
Since both
email and
phone default to
None, it looks like both are optional.
But my requirement is:
at least one of email or phone must be provided — either one or both are valid.
Is there a clean way to express this requirement using
Python type hints? Or is the best approach simply to validate it at runtime? 🤔
I know type hints aren't enforced at runtime, but ideally I'd like the type hint to communicate this requirement clearly.

See i am when try to use flask, i found the thigns we need to store some data in the user's browser's cookie like
from flask import session
session[pending_register_email] = user_email_id@email.com
what i say after i run this in my routes.py's /register endpoing function , this data got saved inthe user's browser's cookie.
But any way i can say after 5 minute this particular session data will be deleted from the browser's cookie?
another thigns keep like this is perfectly ok with no security problem, as later i will do get this value of the pending_regiser_email and verify the otp stored in my server's cache.?

Guys, I have a question about my current project.
Users upload documents to our app, and we currently send the PDF directly to the LLM. The PDFs are around 50–120 pages and can contain tables, handwritten content, etc., so Gemini is becoming very expensive.
My task is to reduce the cost. I tried OCR with image processing, but the extracted data is not accurate.
So, is there any better approach to extract the data without using OCR, while keeping good accuracy and reducing the LLM cost?
Please suggest some approaches, guys.
