Sensor Read Function With Error Handling

MediumPython

Problem

Write a function to read data from a sensor and handle possible errors. Model each sensor attempt as a dictionary with ok and, when successful, value; return the first successful value within max_attempts, or None if every allowed attempt fails. Implement read_sensor(readings, max_attempts) without attempting reads beyond the retry limit.

Constraints

1 <= len(readings) <= 10^4
1 <= max_attempts <= len(readings)
Each reading is a dictionary containing an ok boolean
A successful reading contains a numeric value
Return the first successful value within the allowed attempts

Function Signature

def read_sensor(readings, max_attempts):
