MIT 6.0001作业.py文件在Jupyter无法运行求助

Hey there! I totally get why you prefer Jupyter over Spyder—those cell-based notes are a game-changer for organizing your learning. Let’s fix that .txt file loading problem step by step, since this is almost always a working directory mismatch (super common when switching between IDEs!).

Common Fixes to Try #

1. Check Jupyter’s Working Directory #

First, let’s confirm where Jupyter is looking for files. Run this in a new Jupyter cell:

import os
print("Current Jupyter working directory:", os.getcwd())

Compare this path to where your .txt and .py files are stored. If they’re not in the same folder, that’s the issue!

You have three easy ways to fix this:

• Move your files: Drag the .txt file into the folder Jupyter is using (the path printed above).
• Use an absolute path in your code: Replace the relative path in your script with the full path to the .txt file. For example:

  # Replace this with your actual file path
  with open("/Users/your-username/Documents/MIT-60001/pset2/words.txt", "r") as file:
      # Your code here
  

• Change Jupyter’s working directory: Run this cell to switch to the folder where your assignment files live:

  os.chdir("/path/to/your/pset2/folder")
  # Verify the change
  print("Updated working directory:", os.getcwd())
  

2. Double-Check File Names & Encoding #

• Make sure the .txt file name in your code matches the actual file exactly—watch for typos, extra spaces, or hidden suffixes (like words.txt.txt if your OS hides file extensions).
• If you hit an encoding error when opening the file, add an encoding parameter to your open() call:

  with open("words.txt", "r", encoding="utf-8") as file:
      # Your code here
  

3. Test File Loading Isolated #

To narrow down the problem, run this simple test cell first. It’ll tell you exactly what’s going wrong:

try:
    with open("words.txt", "r") as f:
        sample_content = f.read()
        print("Success! First 100 characters of the file:\n", sample_content[:100])
except FileNotFoundError:
    print("Oops! The file wasn't found. Double-check your path and file name.")
except Exception as e:
    print(f"Unexpected error: {str(e)}")

Once this test works, your original script should run smoothly too!
