Python报错TypeError：fetch_data()缺少必填参数download_dir求助

Hey there! As a fellow Python learner, let's walk through this step by step:

First, Fixing the fetch_data() Argument Error #

That TypeError is telling you exactly what's wrong: when you call the fetch_data() function somewhere in your code, you aren't passing the required download_dir parameter it needs.

• Double-check where you call fetch_data() in your prism.py file. It should look something like this:

  fetch_data(download_dir="C:/Users/YourName/Downloads")  # Or a relative path like "./downloads"
  

• Make sure you're providing a valid directory path (either absolute or relative) as that argument.

What to Do About Your New Error #

You don't need to create a new post! Stack Overflow works best when you update your original question with new details. Here's what to add:

• Paste the full new error message (including the error type, traceback, and line number where it occurs)
• Include the specific code snippet that's triggering the new error
• List any steps you've already tried to fix it (even if they didn't work!)

Quick Tips for New Python Devs #

• Always read error messages carefully—they usually point directly to the problem (like the missing argument here)
• Use print statements or a debugger to check what values are being passed to functions if you're unsure
• When asking for help, share minimal, reproducible code so others can easily test and debug with you
