It's important to note that several other writers have won the Pulitzer for Fiction at a young age, including:
* Harper Lee: She won in 1961 for "To Kill a Mockingbird" at the age of 34.
* Philip Roth: He won in 1969 for "Portnoy's Complaint" at the age of 35.
* Toni Morrison: She won in 1988 for "Beloved" at the age of 51. However, she had already established herself as a prolific and acclaimed writer by that point.
Therefore, while Lahiri may be one of the youngest, it's difficult to say definitively who holds the title of "youngest" without a precise definition of what constitutes "young."
