When you execute a Python program, the Python interpreter doesn't directly execute the .py file; instead, it parses the source code, compiles it into bytecode(a low-level representation of the Python source code), and stores it as the .pyc file. Further, this bytecode is executed with the Python Virtual Machine (PVM). A .pyc file is usually created when a Python program is ... Read More
