The .py, .pyc, .pyo and .pyd files have their own significance when it comes to executing python programs. They are used for − .py: The input source code that you've written. .pyc: The compiled bytecode. If you import a module, python will build a *.pyc file that contains the bytecode to make importing it again later easier (and faster). .pyo: A *.pyc file that was created while optimizations (-O) was on. .pyd: A windows dll file for Python. In Python, there are several file extensions that are used to indicate different types of files. Here are some of the most ... Read More

In Python, .pyc files are compiled bytecode files that are generated by the Python interpreter when a Python script is imported or executed. The .pyc files contain compiled bytecode that can be executed directly by the interpreter, without the need to recompile the source code every time the script is run. This can result in faster script execution times, especially for large scripts or modules. .pyc files are created by the Python interpreter when a .py file is imported. They contain the "compiled bytecode" of the imported module/program so that the "translation" from source code to bytecode (which only needs ... Read More

Yes, we can write a method using variable arguments once you use variable arguments as a parameter method while calling you can pass as many numbers of arguments to this method (variable number of arguments) or, you can simply call this method without passing any arguments.ExampleLive Demopublic class Sample{    void demoMethod(String... args) {       for (String arg : args) {          System.out.println(arg);       }    }    public static void main(String args[] ){       new Sample().demoMethod("ram", "rahim", "robert");       new Sample().demoMethod("krishna", "kasyap");       new Sample().demoMethod();    } }Outputram rahim robert krishna kasyap

If a function is inline, the compiler places a copy of the code of that function at each point where the function is called at compile time. Any change to an inline function could require all clients of the function to be recompiled because compiler would need to replace all the code once again otherwise it will continue with old functionality. No, Java does not provide inline functions it is typically done by the JVM at execution time.
