Python

On this page, we get you up and running with Sentry's SDK, so that it will automatically report errors and exceptions in your application.

Install

Sentry captures data by using an SDK within your application’s runtime.

Install our Python SDK using pip:

Copied
pip install --upgrade sentry-sdk

Configure

Configuration should happen as early as possible in your application's lifecycle.

Once this is done, Sentry's Python SDK captures all unhandled exceptions and transactions.

Copied
import sentry_sdk

sentry_sdk.init(
    "https://examplePublicKey@o0.ingest.sentry.io/0",

    # Set traces_sample_rate to 1.0 to capture 100%
    # of transactions for performance monitoring.
    # We recommend adjusting this value in production.
    traces_sample_rate=1.0,
)

Verify

This snippet includes an intentional error, so you can test that everything is working as soon as you set it up:

Copied
division_by_zero = 1 / 0

Or, by manually generating an event:

In Python you can either capture a caught exception or the one currently held in sys.exc_info() by not passing an argument:

Copied
from sentry_sdk import capture_exception

try:
    a_potentially_failing_function()
except Exception as e:
    # Alternatively the argument can be omitted
    capture_exception(e)

To view and resolve the recorded error, log into sentry.io and open your project. Clicking on the error's title will open a page where you can see detailed information and mark it as resolved.

You can edit this page on GitHub.
