Why Do My Python Database Integers Have an 'L' Suffix?

Why Do Integers in Database Row Tuples Have an 'L' Suffix?

The 'L' suffix on integer values in a MySQL row's tuple arises from the historical distinction between integers and long integers in Python versions prior to Python 3.

In these earlier Python versions, long integer literals required an 'l' or 'L' suffix to differentiate them from ordinary integers. This distinction served a practical purpose because long integers could handle larger numeric values than traditional integers.

When accessing data from a database with Python, the returned values often appear as long integers, denoted by the 'L' suffix. This occurs because the database stores numeric values as long integers by default to ensure precision and avoid overflow.

To remove the 'L' suffix, you can explicitly convert the integer value using the built-in int() function, as demonstrated in the question. However, in Python 3, the distinction between int and long has been eliminated, and all integers are now represented as a single type called int, which behaves much like the previous long type.
