IDEs for Python

Python shell can be used to write and execute simple programs but it is not suitable for a complex application development. For that purpose, an Interactive Development Environment(IDE) is required. An IDE provides many features such as intellisense, auto code generation, searching references of methods etc. Any one of the following IDEs can be used for python development.

  1. Atom
  2. Visual Studio Code
  3. PyCharm
  4. IDLE

Any of the above can be used for writing python code.

Note: An IDE is suitable for larger application development. For smaller programs and learning purposes, it is better to start with writing on a Notepad so that you remember syntax.
