Example result
Code review: Python order-import script for a small online shop
What the code does
- Reads
orders.csvfrom the shop export. - For each order line, finds the product by SKU in
stock.xlsxand subtracts the quantity. - Writes the updated stock back and logs totals to
import_log.txt.
The structure is clear and functions are well named. Most issues are about input that does not look the way the script expects.
Bugs and weak spots
| # | Line | Severity | Issue |
|---|---|---|---|
| 1 | 48 | High | The same CSV can be imported twice; there is no check for already processed order IDs. This is the most likely cause of negative stock. |
| 2 | 72 | High | int(row["qty"]) crashes on empty or "2.0" values from refunded orders. |
| 3 | 95 | Medium | SKU lookup is case-sensitive: "gt-101" and "GT-101" are treated as different products. |
| 4 | 130 | Medium | The file is opened without encoding="utf-8", so product names with accents break on Windows. |
| 5 | 201 | Low | Bare except: hides real errors and makes the log useless. |
Corrected fragments
Issue 1: skip orders already imported
processed = load_processed_ids("processed_orders.txt")
for row in reader:
if row["order_id"] in processed:
continue
# ... existing logic ...
processed.add(row["order_id"])
save_processed_ids("processed_orders.txt", processed)
Why: each order is applied once, even if you run the script on the same file again.
Issue 2: read quantity safely
raw = (row.get("qty") or "").strip()
try:
qty = int(float(raw))
except ValueError:
log.warning("Order %s: bad quantity %r, skipped", row["order_id"], raw)
continue
Why: refunded or partial lines are skipped with a clear note instead of stopping the whole import.
Issue 3: normalise SKUs
sku = row["sku"].strip().upper()
Apply the same .strip().upper() when building the stock dictionary.
Style and readability
process()is 90 lines long; split it intoread_orders,apply_to_stock,write_report.- Replace magic column numbers (
row[7]) with header names.
Please test each fix on a copy of your files: we read the code but did not run it.
Client: owner of a tea shop who wrote a 310-line Python script that imports orders from a CSV export into the stock spreadsheet Problem reported: "Sometimes stock goes negative, and the script crashes on some files."
The client and all details are made up.
About this service
GDScript is easy to start with, but indie projects pick up trouble along the way: Godot 3 syntax in a Godot 4 project, node paths that break when the scene tree changes, signals connected twice, physics done in _process and untyped variables hiding bugs. We read your scripts, explain how the nodes and signals talk to each other, and mark the bugs and fragile spots. Corrected fragments use Godot 4 syntax with @export, @onready, await and static typing where it helps.
What is included
- What you getA written review on the order page: how your nodes and signals work together, issues by importance and corrected GDScript fragments. Premium adds a plan for organising scenes and autoloads as the game grows.
- Godot 3 to 4 syntaxyield, export and onready updated
- Node pathsFewer fragile get_node calls
- SignalsConnected once, in the right place
- Process vs physicsMovement in the right callback
- Static typingTypes that catch mistakes early
How it works
- 1BriefYou paste scripts and the scene tree
- 2ReadingWe follow nodes and signals
- 3ReviewYou get issues and corrected GDScript
What we need from you
The GDScript files pasted as text, a screenshot of the scene tree, the Godot version, what should happen and the errors from the Debugger panel.
We will ask you:
- Which Godot version are you on?
- Is the game 2D or 3D?
- Which mechanic does the script handle?
- What goes wrong in the game?

- Fixed priceThe package price does not change after you pay.
- The money is reservedWhen you pay, the amount is only reserved. It is released to the service once you accept the work.
- Checked before deliveryEvery result goes through a quality check before it reaches you, and you see it on the order page before accepting it.
- Free revisionsAsk for changes within your brief as many times as the package allows.
- Acceptance after 3 daysIf within 3 days of delivery you neither accept the work nor ask for changes, it is accepted automatically. If you write in the order chat after delivery, the order waits; once we answer, we may start the 3 days again and will say so in the chat.
- Redo or a full refundIf the result does not match your brief and the revisions did not fix it, or the work takes more than twice its deadline, write in the order chat: we will redo the work or refund the payment in full.
Questions and answers
Do you run my code?
No. We read it carefully and reason about how it behaves, but we do not execute it, so test every suggested fix in your own project.
Can you help me port a project from Godot 3 to 4?
Yes, for the scripts you send. We mark every line that changed meaning in Godot 4 and give the new version.
Do you review C# in Godot?
Yes, Godot C# scripts fit too. Tell us which language each file uses.
