Import Multiple Files From a Folder in Python

Below, are the methods of importing multiple files from a folder in Python.

  • Using os and open
  • Using glob Method
  • Using pandas Method

File structure :

 index.txt : w3wiki
 index.csv : w3wiki
 index.tsv : w3wiki
 index.html : <h1>w3wiki</h1>

Import Multiple Files From A Folder using OS and Open

In this code example, below code utilizes the `os` module to list files in the “templates” folder. It then iterates through the files, reads those with a “.txt” extension, and prints their content. The script uses the `open` function to access each file, reads its content.

Python3 
import os

folder_path = "templates"
files = os.listdir(folder_path)

for file in files:
    if file.endswith(".txt"):
        file_path = os.path.join(folder_path, file)
        with open(file_path, 'r') as f:
            data = f.read()
            # Process the data as needed
            print(f"File: {file}\nData:\n{data}\n{'=' * 30}")

Output

File: index.txt
Data:
w3wiki
==============================

Import Multiple Files From A Folder using glob Method

In this example, below uses the glob module to create a list of CSV files in the “templates” folder. It then iterates through the list, opens each file, reads its content, and prints file information along with the data. The script employs the os.path.join function to construct the file path and displays a separator line after each file’s data.

Python3 
import glob
import os

folder_path = "templates"
csv_files = glob.glob(os.path.join(folder_path, '*.csv'))

for file in csv_files:
    with open(file, 'r') as f:
        data = f.read()
        # Process the CSV data as needed
        print(f"File: {file}\nData:\n{data}\n{'=' * 30}")

Output

File: templates\index.csv
Data:
w3wiki
==============================

Import Multiple Files From A Folder using pandas Method

In this example, below Python code the `Pandas` library to read multiple HTML files from the “templates” folder. It uses `glob` to create a list of HTML files, reads each file into a Pandas DataFrame, and concatenates them into a single DataFrame named `combined_data`. The final DataFrame can be further processed as needed, and its contents are printed.

Python3 
import pandas as pd
import glob
import os

folder_path = "templates"
csv_files = glob.glob(os.path.join(folder_path, '*.html'))

dfs = [pd.read_csv(file) for file in csv_files]
combined_data = pd.concat(dfs, ignore_index=True)

# Process the combined_data dataframe as needed
print(combined_data)

Output

Empty DataFrame
Columns: [<h1>w3wiki</h1>]
Index: []
