Pandas: Multiple CSVs in one Zip file

[Abdur-Rahmaan Janhangeer]

Greetings,

Cannot read one file in a zip file if the zip file contains multiple files.

This example does not work https://www.py4u.net/discuss/203494 as Pandas
shows a ValueError: Multiple files found in ZIP file. Only one file per ZIP.

If the Zip file has one file, fine else i cannot find a way. Thanks

Kind Regards,

You may have introduced an error when you translated the snippet to your
use case. What went wrong is hard to guess unless you provide the exact
failing code.

Pandas can read a single zipped file out of the box and the accepted
answer in your indirect link to

https://stackoverflow.com/questions/61971040/python-extract-csv-files-from-multiple-zip-files-and-combine-the-data

shows how to deal with zip files containing multiple files.

Is it possible that you are trying to treat the zip file as a gzip file?
Those are different file formats with different purposes (archive vs.
stream), but they use the same compression algorithm, and the gzip tool
(and - I presume - also the gzip library) can read a zip file with a
single member. The error message would match that.
