How To Get Filename Extensions In Python?

Python is a strong, adaptable, high-level, popular, and all-purpose programming language. It is easy to read, clear, and capable of carrying out any activity, making it a great first language. Its design philosophy, which heavily relies on indentation, prioritizes code readability. Web applications may be created on a server using Python because it supports a variety of programming paradigms, including functional, object-oriented, and structured programming.

Python filename extensions

Python has a syntax akin to English in that it is straightforward to understand. Since Python is a general-purpose programming language, in contrast to the other languages available, it can be used for software development and other forms of programming outside web development. It helps with software development, data science, back-end development, arithmetic, and system programming. 

Cross-platform compatibility is a feature of Python, which implies that programs written in it may run on various operating systems, including Windows, Mac OS, Linux, Raspberry Pi, and others. Python works on an interpreter system, so code may be executed immediately after it is created, making it excellent for prototyping. A file having Python filename extensions are file having the python files in them with

Widely used Python filename extensions are:

  • .py
  • .pyo
  • .pyw
  • .pyi
  • .pyc
  • .pyz
  • .pyd

Example: temp.py

Python scripts may be run by using the .py, .pyc, .pyo, and .pyd python filename extension; each of which has a specific purpose as given below:-

  • .py: The Python source code is located in this file
  • .pyc: Contains the compiled bytecode. 
  • .pyo: .pyc file with optimizations on.
  • .pyd: A windows Dynamic-link library file for Python.

Methods to get filename extensions in Python

Using one of the two distinct methods shown below, we may get an answer to the question of “how to get filename extensions in Python?”:

Method 1: Using Python os module splitext()

The splittext() function separates the file path string into the file name and file extensions into a pair of roots and extensions so that we can put them both together to get the file path back. When the OS module is already in use, this function should be used. 

file name + extension = path 

import os
split_fl = os.path.splitext('temp.py')
#print the splitting of path where filename is 0 and extension is 1
print(split_fl)
file_ext = split_fl[1]
#print file extension
print(" ", file_ext)

Output:

('temp', '.py')
.py

Method 2: Using Pathlib module

For an object-oriented strategy, this method is preferred in order to get file extensions. To extract the file path extension, use the pathlib.Path().suffix function of the Pathlib module.

import pathlib
file_ext = pathlib.Path('temp.py').suffix
#print file extension
print(" ", file_ext)

Output:

.py

You can compile it with online python compiler.

Frequently Asked Questions

Is PYC quicker than Python?

PYC (Python Compiled File) is not inherently quicker than Python source code. PYC files are a compiled form of Python code, but the execution speed depends on the Python interpreter, not the file format. Compiled code may load faster, but runtime performance depends on the interpreter's optimization.

What do .py and .PYC files stand for?

Program source code will be found in py files. At the same time, the bytecode for your application is included. pyc file. Each Python filename extension has its purpose.

Bytecode in Python: What is it?

You may think of the Python interpreter's bytecode as a set of instructions or a simple program. It comes in.pyc of Python filename extensions.

Where can I find PYC files?

By default, the __pycache__ directory is generated on the same directory level as a source code file. pyc files from the same directory are kept in this directory.

How do I convert Python filename extensions from py to pyc?

There are a few different approaches to converting one Python filename extension to another, but one of them is to use the py compile module.

What is the file extension for a Python file?

The file extension for a Python file is ".py". Python source code files use this extension to indicate that they contain Python programming code and can be executed using a Python interpreter.
