Select Your Workspace
Several educational platforms now offer coding exercises that can be completed directly within the browser, eliminating the need for local installations. An example of this is DataCamp’s learning platform, which allows users to learn coding without requiring any downloads. However, for optimal learning, it is recommended to have an Integrated Development Environment (IDE) installed on your personal computer. It is advisable to explore different marketplaces that provide a variety of IDE options, as each platform may offer unique features and improvements compared to others.
- Anaconda: Anaconda is a comprehensive toolkit that caters to all your coding needs. It provides various environments like Powershell prompt, Jupyter Notebook, PyCharm, and even supports R Studio if you’re interested in exploring R programming.
- Atom: Atom is a Python interface that offers advanced functionalities and comes highly recommended by experts.
- Google Colab: Google Colab is a cloud-based platform similar to Jupyter Notebook. It eliminates the need for local installations as all the essential libraries like NumPy, Pandas, Matplotlib, and Sci-kit Learn are already pre-installed.
- PyCharm: PyCharm is an exceptional IDE that facilitates integration with libraries such as NumPy and Matplotlib. It allows you to work with array viewers and interactive plots, enhancing your programming experience.
- Thonny: Thonny is an IDE specifically designed for teaching and learning programming. It includes features like a debugger, code completion, and syntax error highlighting to support beginners in their programming journey.
