What commenters say

• Some developers prefer using print statements for debugging, while others advocate for more advanced tools like pdb and IPython.
• PyCharm is considered a powerful IDE for Python development, but some users find its features overwhelming or prefer more lightweight editors like Sublime Text or VSCode.
• The use of a debugger can significantly improve the debugging process, especially for complex issues, but some developers rely on logging and print statements for simpler problems.
• The choice of debugging tool or method often depends on personal preference, the type of project, and the level of complexity involved.
• Some developers appreciate the remote development features of VSCode, while others find PyCharm's implementation lacking in this area.
• The importance of understanding code and being able to reason about it is emphasized, with some arguing that relying too heavily on IDE features can hinder this understanding.
• Learning to use a debugger properly can be beneficial for efficient debugging, and resources like online courses and tutorials are available to help developers improve their skills.
