=={{header|Python}}==
Python uses the [[wp:Mersenne twister|Mersenne twister]] algorithm accessed via the built-in [http://docs.python.org/library/random.html random module].
=={{header|Tcl}}==
Tcl uses a [[wp:Linear congruential generator|linear congruential generator]] in it's built-in <code>rand()</code> function. This is seeded by default from the system time, and kept per-interpreter so different security contexts and different threads can't affect each other's generators (avoiding key deployment issues with the rand function from [[C]]'s math library).
