    In this method, the process gain (k p) is equal to the change in output divided by the change in input. The dead time θ is the amount of time between when the step change occurred and when the output first changed. The time constant (τ p) is the amount of time it takes for the output to reach 63.2% of the new steady-state value after the step ...

    A Generation Data Group [10] (GDG) [11] is a group of non-VSAM data sets [12] that are successive generations of historically-related data [13] stored on an IBM mainframe (running OS or DOS/VSE). [14] A GDG is usually cataloged. [13] An individual member of the GDG collection is called a "Generation Data Set."

    This allows for many radical things to be done syntactically within Python. A new method resolution order for multiple inheritance was also adopted with Python 2.3. It is also possible to run custom code while accessing or setting attributes, though the details of those techniques have evolved between Python versions.

    en.wikipedia.org/wiki/Zen_of_Python

    The Zen of Python is a collection of 19 "guiding principles" for writing computer programs that influence the design of the Python programming language. [1] Python code that aligns with these principles is often referred to as "Pythonic". [2] Software engineer Tim Peters wrote this set of principles and posted it on the Python mailing list in ...

    But if exact values for large factorials are desired, then special software is required, as in the pseudocode that follows, which implements the classic algorithm to calculate 1, 1×2, 1×2×3, 1×2×3×4, etc. the successive factorial numbers. constants: Limit = 1000 % Sufficient digits.

  9. Stackless Python - Wikipedia

    en.wikipedia.org/wiki/Stackless_Python

    Stackless Python, or Stackless, is a Python programming language interpreter, so named because it avoids depending on the C call stack for its own stack. In practice, Stackless Python uses the C stack, but the stack is cleared between function calls. [ 2 ]
