1. • They are imported

     • The reason some files get compiled automatically is because they are imported; for instance, if you use import mylib.py, Python will compile mylib.py so that future import statements run a little faster. If you later change mylib.py, then it will get re-compiled next time it is imported (Python uses the file date to see that this happens.)

   May 20, 2024 · Understanding the differences between these two types of files is essential for efficient Python programming and debugging. '.py' files contain human-readable source code written by developers, while '.pyc' files are compiled bytecode generated by the Python interpreter to speed up module loading.

   Feb 26, 2012 · Python has a compiler! You just don't notice it because it runs automatically. You can tell it's there, though: look at the .pyc (or .pyo if you have the optimizer turned on) files that are generated for modules that you import. Also, it does not compile to the native machine's code.

   May 16, 2024 · Compiled Python modules can only run on matching interpreter versions. The solution is to create multiple built distributions, one for each of the targeted Python versions, with matching compiled modules.

   Dec 7, 2021 · Luckily, it’s pretty simple to find out if an executable file is a compiled Python, using the following method: Use the resource section (part of the PE file format) to locate compiled Python identifiers, such as the widely known icon.

   When Python code is compiled, it goes through the following steps: The source code is parsed to create an abstract syntax tree (AST). The AST is then compiled into bytecode. The bytecode is executed on the Python interpreter. During compilation, the Python compiler checks for syntax errors, ensuring the code will execute correctly once it is run.

   Does compiled Python increase performance?

   • There is a performance increase in running compiled python. However when you run a .py file as an imported module, python will compile and store it, and as long as the .py file does not change it will always use the compiled version. 1. File is processed by the interpeter.

   Should I run a compiled PYC file?

   • The advantage of running a .pyc file is that Python doesn't have to incur the overhead of compiling it before running it. Since Python would compile to byte-code before running a .py file anyway, there shouldn't be any performance improvement aside from that. How much improvement can you get from using compiled .pyc files?

   Does a Python file run faster than a compiled file?

   • "An Introduction to Python" says this about compiled Python files: A program doesn't run any faster when it is read from a ‘.pyc’ or ‘.pyo’ file than when it is read from a ‘.py’ file; the only thing that's faster about ‘.pyc’ or ‘.pyo’ files is the speed with which they are loaded.

   When your Python file closes immediately, there is likely an error in your code. The error could be related to syntax, logical errors, or runtime errors. Use a debugger to identify and locate the errors in your code. Several debugging tools are available for Python, including pdb and PyCharm.
