Instrumentation of Python Bytecode and Symbolic Program Analysis
As part of a project to help non-programmers understand computer programs, the goal of this work was to generate information on the behaviour of Python programs. The implementation described in this work uses an approach based on instrumenting Python bytecode to trace back variable assignments in order to build a graph depicting how the output of the program depends on its intermediate and input values. The presented version of the implementation enables the user to analyze simple programs by visualizing the data flow occurring during to the computation of a program’s output.
