.P File Extension

A P file is a pickle file created by pickle, a Python module used for converting Python objects to a byte representation for storage on disk or transfer over a network. It allows for objects to be conveniently stored or transmitted without first having to convert the data to another format. P files can be "unpickled" and loaded back into program memory during runtime.

A P file is a source code file written in the Pascal programming language. It contains Pascal source code that can be edited with a Pascal development program or a basic text editor. P files can be compiled into executable programs using a Pascal compiler such as Turbo Pascal.

Pascal was originally developed in the late 1960s and published in 1970 by Niklaus Wirth. It is a procedural language that has led to several different variants such as Super Pascal and Pascal Sol. Object Pascal is also an extension of Pascal that was developed in 1985 and designed for object-oriented programming at Apple Computer. P files are one of several files used to store Pascal source code, along with the more common .PAS file.
