How can I run a Python script online for free?

To run a Python script online for free, you can make use of various online Python interpreters or cloud-based development environments. Here are some popular options:

  1. ( is an online IDE that supports multiple programming languages, including Python. It allows you to create and run Python scripts directly from your browser. You don’t need to install anything locally, and it offers features like collaborative coding, version control, and sharing.
  2. Google Colab ( Google Colab is a cloud-based Jupyter notebook environment that allows you to write and run Python code. It’s particularly useful for data analysis, machine learning, and AI-related tasks. You can also access and utilize GPU and TPU resources for faster computation.
  3. JDoodle ( JDoodle is an online compiler and IDE that supports Python and many other languages. It offers a simple interface to write and execute Python scripts online.
  4. PythonAnywhere ( PythonAnywhere is a platform that provides cloud-based Python development environments. It allows you to write, run, and host Python scripts and web applications online. While it offers free plans, there might be some limitations on resources.
  5. ideone ( ideone is an online compiler and debugging tool that supports Python. It lets you write and run code snippets online and share them with others.

Remember that while these online environments are convenient for quick testing and coding, they might have some limitations regarding runtime, resource usage, or available libraries compared to running Python scripts locally on your computer. For more extensive projects, it’s recommended to use a local Python development environment.

Which One is Favorite?

Google Colab (

Google Colab is a cloud-based Jupyter notebook environment developed by Google. It offers a rich set of features, including:

  1. Free GPU and TPU Access: Google Colab provides free access to GPU (Graphics Processing Unit) and TPU (Tensor Processing Unit) resources, which is incredibly valuable for computationally intensive tasks like machine learning and deep learning.
  2. Seamless Integration with Google Drive: You can easily save and load notebooks from Google Drive, making it convenient for managing your projects and datasets.
  3. Vast Library Support: Google Colab comes pre-installed with many popular Python libraries, and you can easily install additional libraries as needed.
  4. Collaboration: Just like other online platforms, you can share your notebooks with others, allowing for easy collaboration and code sharing.
  5. Markdown Support: You can mix code and explanatory text using Markdown cells, making it great for documenting and explaining your code.
  6. Python 3 Support: It supports the latest version of Python 3.

Overall, Google Colab is a powerful and user-friendly online environment that suits a wide range of Python tasks, particularly for data analysis, machine learning, and AI-related projects. However, the choice of an online Python environment ultimately depends on your specific needs and preferences. Feel free to explore different platforms and select the one that best fits your requirements.

Pros and Cons of Online Editors

Let’s explore the pros and cons of using online Python environments.


  1. No Installation Required: The most significant advantage is that you don’t need to install Python or any related libraries on your local machine. This makes it extremely convenient and accessible, especially for beginners or users who don’t want to deal with installation and setup procedures.
  2. Platform Independence: Since online Python environments run in a web browser, they are platform-independent. You can use them on any operating system, including Windows, macOS, Linux, or even mobile devices.
  3. Cloud Storage and Collaboration: Online platforms often provide cloud storage, allowing you to save and access your Python code from anywhere with an internet connection. Many platforms also support real-time collaboration, making it easy to work with others on the same codebase.
  4. Pre-installed Libraries and Packages: Some online environments come with pre-installed Python libraries and packages, saving you the trouble of installing them manually. This can be beneficial when you need to use specific libraries without the hassle of setup.
  5. Accessible Resources: Some online Python environments, like Google Colab, provide access to powerful hardware resources, such as GPUs and TPUs, for computationally intensive tasks like machine learning and data analysis.
  6. Shareability: Online environments often allow you to share your code or projects easily with others, making it simple to showcase your work or get help from the community.


  1. Limited Resources: Online environments may have limitations on resource usage, such as CPU, memory, or storage. For large or resource-intensive projects, this can be a significant drawback.
  2. Internet Dependency: Since the environment is online, you need a stable internet connection to access and work on your code. If you are in a location with poor connectivity or no internet access, you won’t be able to use the platform.
  3. Privacy and Security Concerns: Uploading and running code on a third-party platform means you are entrusting them with your code and data. While reputable platforms take security seriously, there’s always a small risk associated with using cloud-based services.
  4. Limited Offline Access: Unlike a local development environment, online platforms might not provide full offline access to your code. Some platforms offer offline modes, but they may have limitations compared to their online counterparts.
  5. Learning Environment Limitations: Online environments might not provide the same level of control and flexibility as setting up a local Python environment. Learning how to set up your own development environment is an essential skill for any serious Python developer.
  6. Service Dependency: If the online platform shuts down or changes its services, it may impact your workflow or access to your code and data.

In summary, using online Python environments can be incredibly convenient for quick testing, learning, and collaborating with others. However, for more significant projects or if you require full control over your development environment, setting up a local Python environment might be a better choice. It’s essential to consider your specific needs and priorities when deciding between online and local Python development.
