Utility wrapper class to handle exceptions.
Python >= 3.8
You can install trier from PyPI, with pip:
python -m pip install trierInstead of using try except block you could replace it with trier.
from trier import Try
err, val = Try(lambda: 10 / 0).catch(ZeroDivisionError)
if err:
# handle error
# do stuff with `val`
# Another way to handle could be
if not err:
# do stuff with `val`Supports multiple exceptions.
from trier import Try
err, file = Try(open, file="doenot_exist.txt").catch(FileNotFoundError, OSError)
if err:
# handle error
# do stuff with `file`Supports async error handling as well.
import asyncio
from httpx import AsyncClient, HTTPStatusError, Response
from trier import Try
def raise_on_4xx_5xx(response):
response.raise_for_status()
async def main():
client = AsyncClient(event_hooks={"response": [raise_on_4xx_5xx]})
# The endpoint responds with a 404 error
err, response = await Try(client.get, "https://run.mocky.io/v3/201f1fe6-5a3b-49c1-9df7-312951618405").async_catch(HTTPStatusError)
if err:
# Handle error
# do stuff with `response`
