  1. Python automatically compiles your script to compiled code, so called byte code, before running it. Running a script is not considered an import and no .pyc will be created. For example, if you have a script file abc.py that imports another module xyz.py, when you run abc.py, xyz.pyc will be created since xyz is imported, but no abc.pyc file ...

  2. Aug 10, 2023 · Step 4: Byte code that is .pyc file is then sent to the Python Virtual Machine (PVM) which is the Python interpreter. PVM converts the Python byte code into machine-executable code and in this interpreter reads and executes the given file line by line.

  3. .py source code is first compiled to byte code as .pyc. This byte code can be interpreted (official CPython), or JIT compiled (PyPy). Python source code (.py) can be compiled to different byte code also like IronPython (.Net) or Jython (JVM). There are multiple implementations of Python language. The official one is a byte code interpreted one.

  4. Mar 7, 2024 · Whenever the Python script compiles, it automatically generates a compiled code called as byte code. The byte-code is not actually interpreted to machine code, unless there is some exotic implementation such as PyPy .

  5. Dec 30, 2023 · This deep dive explores if Python is interpreted, compiled, or uniquely both, profoundly impacting how developers approach their craft.

  6. Feb 25, 2024 · Understanding Bytecode is like having a backstage pass to a Python performance. It offers insights into: Efficiency: By examining Bytecode, you can pinpoint bottlenecks in your code. Portability: Bytecode is why Python code can run across platforms without modification.

  8. It's important to know, that Python Source Code is compiled to Byte Code in a first step, just to understand the difference between Syntax Errors (which appear in the compilation step) and cxceptions, which appear at runtime.
