speeder | Speed reading engine in Javascript

I tried completely different approach and deliberately increased the size of your data by 500. The solution I propose is 5 times faster for 500 times larger dataset, and should be more and more faster if the size of the data increase.

Its reason for you may be load all the details included avatar image(user image) so, If you dont needed then load like this way,

• I would encourage you to use Option Explicit which will force you to declare all variables which among others, will make the code more readable, unexpected behavior (errors) easier traceable... It is a little more work, but in the long run, it will surely pay off.

A Quick Fix

So your error is that you never call plotsir(t, S, I, R). And plt.show() doesn't work with streamlit. Use instead st.pyplot(). The working code:

Unless specified otherwise, mock would return default value.

It doesn't call base class implementation.

The problem here is that you want to check presence of a key in two (other) tables, and you cannot enforce that using foreign key constraints on a single column. Postgres allows you to create CHECK expressions for custom checks, but as the manual says:

PostgreSQL does not support CHECK constraints that reference table data other than the new or updated row being checked. (...) If possible, use UNIQUE, EXCLUDE, or FOREIGN KEY constraints to express cross-row and cross-table restrictions.

If what you desire is a one-time check against other rows at row insertion, rather than a continuously-maintained consistency guarantee, a custom trigger can be used to implement that.

See this very related question for different solutions.

Some databases (MS SQL Server) allow you to use a function in CHECK expressions. That would be optimal, but Postgres does not allow that syntax.

For PostgreSQL, you need to create a TRIGGER that will execute when something is inserted into items_for_sale. That, on the other hand, does allow functions or cross-table checks.

It would look something like this:

Given your code there's two reasons this could be happening. The first is that you're including a fragment in the URL, eg. yourdomain.com/page#myform. If the fragment matches the id of an element in the DOM then when the page loads it will scroll to that element. To stop this, remove the fragment or change the id of the element.

Also you're calling focus() on an input element. This sets the caret in to the field and also scrolls it in to view. If you don't want this to occur, remove the call to focus().

Part of your problem is I think a misunderstanding of what pickle does and is intended for.

It can be used to preserve a save state, just not the way you're doing it.

Lets start with the error you're getting. There is no game function defined in the file your python file that you are calling it from. So you cant use game(). You would need to call it with fun.game().

Secondly, your game function is returning a dict with some empty list values and some False values so this is not the state you want to preserve anyway.

Finally, what pickle is intended for is serializing python objects such as dicts into bytes. The reason you'd want to do that is because you can then transfer those bytes over a socket or save them to a text file.

To load that saved dict or object you would then need to read the text file or receive the byte string through a socket and unpickle and voila, you have an object.

To test it and help you see how it works, hop into the python console and run these commands.

Continuing from the comments in the quesiton:

OP:

I am getting errors such as If the person is at the sped limit the code should stop if hes over the code should carry on, and I cnt figure out how when he inputs letters asks fo the question again

Ans:

You need a except ValueError: to catch the invalid types. Also, I have fixed a few other bumps.
