Usage

Example 1: Handling Exceptions

from commonpy.simpleexceptioncontext import SimpleExceptionContext

callback = lambda e: self._eng.statusChanges.emit(f'Exception in processing {e}')
with SimpleExceptionContext('exception in processing',callback=callback):
    ret=self.process_internal(ls)
    logging.debug(f"process end {ret}")
    return ret

In this example , a callback is called when the exception occurs.

Example 2: Exception Handling with Decorators

@simple_exception_handling(err_description='error in get_symbol_history', return_succ=(None, []), never_throw=True)
@excp_handler(polygon.exceptions.BadResponse, handler=excphandler)
def get_symbol_history(sym, startdate, enddate, iscrypto=False):
    # Your code to fetch symbol history here
    pass 

Example 3: Date and Time Utilities

from commonpy import localize_it, unlocalize_it
import datetime

dt = datetime.datetime.now()
localized_dt = localize_it(dt)
unlocalized_dt = unlocalize_it(localized_dt)

Features

• SimpleExceptionContext: Context manager for handling exceptions with customizable logging and traceback formatting.
• Date and Time Utilities: Functions to localize and unlocalize datetime objects.
