This code snippet does the following:

1. Creates a Copy of data:

   • to_encode = data.copy() creates a shallow copy of the dictionary data. This ensures that modifying to_encode does not affect the original data dictionary.

2. Sets an Expiration Time:

   • expire = datetime.now(UTC).replace(tzinfo=None) gets the current time in UTC. The replace(tzinfo=None) removes tzinfo (timezone information), making the datetime object naive.
   • expires_delta or timedelta(minutes=SecurityConfig.ACCESS_TOKEN_EXPIRE_MINUTES) determines how much time should be added to the current timestamp. If expires_delta is provided, it will be used; otherwise, a default timedelta is created using SecurityConfig.ACCESS_TOKEN_EXPIRE_MINUTES.

3. Updates the Copy with the Expiration Information:

   • to_encode.update({"exp": expire}) adds or updates the "exp" (short for "expiration") key in the copy of the dictionary to_encode with the computed expiration timestamp.

Summary:

This code prepares a dictionary to_encode by copying an existing dictionary data and adding an "exp" key with an expiration timestamp. This is likely part of a process for encoding data (e.g., for creating a token like a JWT) with a time-based expiration.
