Python项目中如何正确配置图标文件的相对路径？

Hey there! I see exactly where the issue is here—let's break this down and get your icon path working properly.

The Root Cause #

When you use a path starting with a leading slash like /icons/currency/USD.png, you're telling your system to look for this folder starting from the root directory of your operating system (like C:\ on Windows or / on Linux/macOS), not your project's folder. That's why it can't find the file—your icons folder lives inside your project directory, not at the system root.

The Correct Relative Paths #

Since your name_of_project.py is in the root of your project (right next to the icons folder), you have two simple, working options for the relative path:

• Just use the path without the leading slash: icons/currency/USD.png
• Or add ./ at the start to explicitly reference the current directory (where your script lives): ./icons/currency/USD.png

Both of these will tell Python to look inside your project's root, then into icons, then currency, to find USD.png.

A More Robust Approach (Recommended) #

If you want to avoid path issues entirely—especially if you might run your script from different working directories—use Python's built-in modules to dynamically build the path. This way, the path will always be correct no matter where you execute the script.

Using os module:

import os
# Get the directory where your script is located
script_dir = os.path.dirname(__file__)
# Build the full path to your icon
icon_path = os.path.join(script_dir, "icons", "currency", "USD.png")

Using pathlib (Python 3.4+):

from pathlib import Path
# Get the parent directory of your script
script_parent = Path(__file__).parent
# Build the path using intuitive slash notation
icon_path = script_parent / "icons" / "currency" / "USD.png"

Either of these methods will reliably point to your icon file, even if you move the project or run the script from a different folder.
