A scratch file is useful for a temporary experiment that you do not yet want to organize into your main project.
Understanding the Concept
PyCharm offers scratch files through its file creation actions. A Python scratch file can contain valid Python code and be run or inspected, depending on the current IDE setup. Scratch files live in an IDE-managed location instead of being ordinary files in your project folder. That is convenient for quick tests but less appropriate for scripts you intend to share, commit, or maintain.
When and Why You Would Use This
Use scratch files to test a tiny calculation or compare two string operations. Once a snippet becomes useful, move the tested idea into a well-named .py file under the project source folder.
Practical Example
sample_text = "Learning Python"
print(sample_text.lower())
print(len(sample_text))Understanding the Example
The output includes learning python and 15, counting the space. A scratch file can help test the result without changing your main script, but the Python behavior is the same.
Example Output
learning python
15Try It Yourself
Create a Python scratch file, experiment with one expression, and copy the final tested code into a regular project file.
Common Beginner Mistakes
- Assuming scratch files automatically belong to the active project repository.
- Keeping important project functionality only in IDE-specific scratch locations.
- Confusing scratch execution with Python interactive shell behavior.
Key Takeaways
- Scratch files are for disposable experiments.
- They run ordinary Python statements where supported.
- Move useful code into normal project files when it becomes part of the application.
