The lambda function is being bound to the variable test_password, effectively making it a named function. ethan_ is code golfing for fun, which is when you try to complete a challenge with as few characters as possible. Maintainability isn't the goal.

hey man, id say rather just throw it inside a function instead of lambda so it can be used more than just that line and easily modified in the future

This is the nature of Freestyle Sparring. We take turns remixing and refactoring each others code. If you want to make the code shorter, just fork it!🍴

bro im trying to make the code short

My solution uses only 16 digits but still passes all tests.

I unpublished the challenge because as it is now, it is based on a premise flawed on a very fundamental level.

Unfortunately, but it is very, very far from fixed.

Your initial value is still a float, and is accurate up to 16 decimal places max. You cannot turn a 16-digit float into a decimal and expect it to automagically restore 9984 missing digits.

Can you check what reference_pi returns for digits=10000? Does it return 10_000 digits?

done, issue should be fixed now.

fixing...

How exactly returning 10k decimal places works in this task if the return type is float, and float is accurate to 15-16 decimal digits? My solution calculates max 16 digits and passes all tests.

This is very good. will save it and look into.
