The Python interpreter first reads the human code and optimizes it to some intermediate code before interpreting it into machine code. That's why you always need another program to run a Python script, unlike in C++ where you can run the compiled executable of your code directly. For example, c:\Python27\python.exe or /usr/bin/python.
Jul 11, 2015 · 11. I can understand the fact that Java needs both a compiler and an interpreter. It compiles source code to bytecode and then a virtual machine (on Windows, on Linux, on Android, etc.) translates that bytecode to machine code for the current architecture. But why does Python need both a compiler and an interpreter?
Aug 2, 2019 · In various books of python programming, it is mentioned that python language is interpreted. But that is half correct the python program is first compiled and then interpreted. The compilation part is hidden from the programmer thus, many programmers believe that it is an interpreted language. The compilation part is done first when we execute ...
Feb 26, 2012 · The majority of modern high-performance language implementations combine both an interpreter and a compiler (or even several compilers) for maximum performance. Actually, it is impossible to run any program without an interpreter. After all, a compiler is just a program which translates a program from one language to another language.
Aug 10, 2023 · The Python source code goes through the following to generate an executable code. Step 1: The Python compiler reads a Python source code or instruction in the code editor. In this first stage, the execution of the code starts. Step 2: After writing Python code it is then saved as a .py file in our system.
On the contrary C is a compiled language, as one have to compile the source code first according to the machine and then execute. This results is much faster execution. Now coming to Python: A python code (somefile.py) when imported creates a file (somefile.pyc) in the same directory. Let us say the import is done in a python shell or django ...

You never invoke a compiler, you simply run a .py file. The Python implementation compiles the files as needed. This is different than Java, for example, where you have to run the Java compiler to turn Java source code into compiled class files. For this reason, Java is often called a compiled language, while Python is called an interpreted ...
