  2. Undefined variable - Wikipedia

    en.wikipedia.org/wiki/Undefined_variable

    An undefined variable in the source code of a computer program is a variable that is accessed in the code but has not been declared by that code.

    In computing, NaN (/ n æ n /), standing for Not a Number, is a particular value of a numeric data type (often a floating-point number) which is undefined as a number, such as the result of 0/0.

  4. py2exe - Wikipedia

    en.wikipedia.org/wiki/Py2exe

    Before then, py2exe was made only for Python 2, [4] and it was necessary to use an alternative like cx_Freeze for Python 3 code.

  8. File format - Wikipedia

    en.wikipedia.org/wiki/File_format

    File formats often have a published specification describing the encoding method and enabling testing of program intended functionality. Not all formats have freely available specification documents, partly because some developers view their specification documents as trade secrets, and partly because other developers never author a formal specification document, letting precedent set by other ...
