This checkpoint confirms that you can create a file, save changes, run it with Python, and fix a small error yourself.
Understanding the Concept
Create a new practice project and a script called checkpoint.py. Write a greeting and a short calculation. Run it in PyCharm, then from a terminal with the intended interpreter. Verify its output matches a prediction. Next, deliberately introduce one syntax mistake, read the error, and fix it. Finally, change one numeric input and confirm the result changes as expected.
When and Why You Would Use This
The goal is an independent workflow, not memorization. If something fails, identify whether the problem comes from the Python code, the interpreter selection, or the file location. Document the step you used to fix it.
Practical Example
learner_name = "Alex"
item_price = 7
item_count = 3
print("Learner:", learner_name)
print("Total:", item_price * item_count)Understanding the Example
Expected output is Learner: Alex and Total: 21. The program uses concepts you have already seen: assignment, string text, multiplication, and print. No external package is needed.
Example Output
Learner: Alex
Total: 21Try It Yourself
Complete the full workflow without copying commands from an earlier result. Record one problem you encountered and how you resolved it.
Common Beginner Mistakes
- Running a file without checking that the saved name and path are correct.
- Trying to debug source code when the wrong interpreter is selected.
- Considering the checkpoint complete before checking output and fixing a deliberately introduced error.
Key Takeaways
- You should be able to create, save, run, and inspect a Python script.
- A simple terminal run checks that your code works outside the IDE.
- Reading and fixing errors is a core beginner skill.
