Where does the Unnamed: 0 column come from?
Short answer. The index that to_csv saved as a first column.
What is the fix?
Save with index=False.
Remember
| to_csv() writes the index too |
| index=False skips it |
You saved a file, read it back, and got Unnamed zero. Why? To C S V saves the DataFrame. By default it also saves the index. Add index equals False to skip it. Two rules. To C S V writes the index too. Index equals False skips it.
