Why does python add an 'L' on the end of the result of large exponents? [duplicate]
Python supports arbitrary precision integers, meaning you're able to represent larger numbers than a normal 32 or 64 bit integer type. The L tells you when a literal is of this type and not a regular integer.
Note, that L only shows up in the interpreter output, it's just signifying the type. If you print that result instead:
>>> print(25 ** 25)88817841970012523233890533447265625The L doesn't get printed.
In Python 3, these types have been merged, so Python 3 outputs:
