Work with exceptions with thread frequency manufacturer Python-Binance

When using Python-Binance you use Threadedweedwebsocketemanager, exceptions can be a challenge due to its asynchronous nature and there is no direct access to errors. However, there are several ways to effectively deal with exceptions.

Why is it difficult to catch exceptions?

Threadedwebsocketmanager is designed to process internal errors, which means that you do not have direct access to the error message. When the exception appears, Binance will give it call chimneys and you will not receive information about what has made a mistake.

1 Solution: Wrap in a block using a verification

One direct approach is to wrap your code into “try” except the “block”:

`Python

Import the thread

According to Binance Import ThreadedwebSocketmanager

Create a Copy of ThreadwebSocketmanager

Driver = ThreadedwebSocketmanager ()

Def Handle_Expts ():

Try:

Code that can lift an exception

To pass

Except as an exception as e:

Print (F “Error: {e}”)

Run the manager in a separate topic

Thread = thread.Thread (target = handle_exceptions)

Thread.start ()

`

This will be captured by the exception raised by ThreadedwebsoCketmanager and printed the error message. However, remember that this approach may not provide a lot of information about what has confused.

Solution 2: Use the Optional Exception Manager

Another approach is to create a function of optional exceptions that reflect specific exceptions and print appropriate information:

`Python

Import registration

Create registration

Logger = Loggy.GetLGER (__ Name__)

Def Handle_Expts ():

Try:

Code that can lift an exception

To pass

Except for ThreadedwebSocketmanager.ConnectionException as E: E:

Logger.Error (F “Relationship Exception: {e})

Except as an exception as e:

LOGGER.Error (F “other exception: {e})

Run the manager in a separate topic

Thread = thread.Thread (target = handle_exceptions)

Thread.start ()

`

This will also be captured by ThreadedwebsoCketmanager.ConnectionException, as well as all the other exceptions raised by Threadedwebsocketemanager, and print important information about what happened.

Solution 3: Use the registration manager

You can also use a optional registration driver to collect threadedwebsoCketmanager error messages. Here’s an example:

`Python

Import the thread

Import registration

Create registration

Logger = Loggy.GetLGER (__ Name__)

Manogerloger Class (Loggy.handler):

DEF EMIT (Self -recording):

Try:

Code that can lift an exception

To pass

Except as an exception as e:

Super (). EMIT (entry)

Create and run logos

Logger = ThREADEDWEBSOCKETMANGERLGER ()

Thread = thread.Thread (Target = Lambda: Logger.handle ())

Thread.start ()

Your code residue …

`

This will collect messages from ThreadedwebsoCKietmanager’s magazine file.

Conclusion

Although there is no direct way to achieve exceptions with Threadedwebsocketmanager, you can use different methods to effectively decide exceptions. Packing code in blocks using Olzore or Custom Mutor is simple solutions, and the use of registration leaders provides greater flexibility and management. Choose the method that best suits your needs.
