pure_eval

This integration uses pure_eval to safely evaluate additional expressions in the source code and display their values alongside other local variables.

Install

Install sentry-sdk from PyPI with the pure_eval extra or pip install pure_eval executing asttokens.

pip install --upgrade 'sentry-sdk[pure_eval]'

Configure

Add PureEvalIntegration() to your integrations list:

import sentry_sdk
from sentry_sdk.integrations.pure_eval import PureEvalIntegration

sentry_sdk.init(
    dns="https://examplePublicKey@o0.ingest.sentry.io/0",
    integrations=[
        PureEvalIntegration(),
    ],
)

Verify

from types import SimpleNamespace

def main():
    sentry_sdk.init(...)  # same as above

    namespace = SimpleNamespace()
    namespace.d = {1: 2}
    print(namespace.d[1] / 0)

main()

When you run this example script an error will be sent to Sentry. Through the PureEvalIntegration the stack trace of the error will include the values of namespace.d and namespace.d[1] which would not be shown without PureEvalIntegration.
