模块导入问题：是否由Python版本差异导致？

Hey there! Python version mismatches are super common when inheriting code—totally get how frustrating that can be. To help you nail down exactly what’s causing the error, could you share a couple of key details?

What to share first: #

• The exact error message you’re seeing (e.g., SyntaxError: invalid syntax or AttributeError: module 'urllib' has no attribute 'urlopen'). This tells us if it’s a syntax incompatibility, a missing module, or a changed function.
• The specific lines of code that trigger the error. Even a small snippet will go a long way!

Common version differences to check in the meantime: #

Since you’re on Python 3.6.4, here are some frequent pitfalls if the original code was written for a newer or older version:

• Newer Python features (3.7+): If the code uses things like dataclasses, the walrus operator :=, or from __future__ import annotations (for postponed evaluation), these won’t work in 3.6.
• Python 2 vs 3 leftovers: If the code was originally for Python 2, you might run into issues like:
  • print "text" instead of print("text") (Python 2 uses print as a statement, 3 requires it as a function)
  • dict.iteritems() / dict.iterkeys() instead of dict.items() / dict.keys()
  • Modules named ConfigParser (Python 2) instead of configparser (Python 3), or urllib2 instead of urllib.request
• Standard library tweaks: Some functions moved or changed behavior between 3.6 and later versions—for example, pathlib had some additions in 3.7 that aren’t available in 3.6, or asyncio functions that were renamed.

Once you share those error details and code snippets, I can walk you through the exact fixes needed!
