python - reading multiple files contained in a zip file with pandas

Question

I have multiple zip files containing different types of txt files. Like below:

zip1 
  - file1.txt
  - file2.txt
  - file3.txt

How can I use pandas to read in each of those files without extracting them?

I know if they were 1 file per zip I could use the compression method with read_csv like below:

df = pd.read_csv(textfile.zip, compression='zip') 

Any help on how to do this would be great.

Answer 1

You can pass ZipFile.open() to pandas.read_csv() to construct a pandas.DataFrame from a csv-file packed into a multi-file zip.

Code:

pd.read_csv(zip_file.open('file3.txt'))

Example to read all .csv into a dict:

from zipfile import ZipFile

zip_file = ZipFile('textfile.zip')
dfs = {text_file.filename: pd.read_csv(zip_file.open(text_file.filename))
       for text_file in zip_file.infolist()
       if text_file.filename.endswith('.csv')}
