What is bytecode?

Bytecode is a low-level, platform-independent representation of Python source code. The Python interpreter compiles source files (.py) into bytecode files (.pyc).

Main features:

• Platform independence: Bytecode can be executed on any platform where the Python interpreter is installed.
• Speed improvement: The compilation to bytecode occurs once during the first import of a module, saving time on subsequent runs.
• Execution by a virtual machine: Bytecode is executed by the Python virtual machine (PVM), which translates it into machine code.

# Example of creating bytecode
import py_compile

try:
    py_compile.compile('my_module.py') # Compile my_module.py into my_module.pyc
except py_compile.PyCompileError as e:
    print(f"Compilation error: {e}")
