In this article, we will see how to read all CSV files in a folder into single Pandas dataframe. The task can be performed by first finding all CSV files in a particular folder using glob() method and then reading the file by using pandas.read_csv() method and then displaying the content.
Approach:
- Import necessary python packages like pandas, glob, and os.
- Use glob python package to retrieve files/pathnames matching a specified pattern i.e. ‘.csv’
- Loop over the list of csv files, read that file using pandas.read_csv().
- Convert each csv file into a dataframe.
- Display its location, name, and content.
Below is the implementation.
Python3
# import necessary libraries import pandas as pd import os import glob # use glob to get all the csv files # in the folder path = os.getcwd() csv_files = glob.glob(os.path.join(path, "*.csv" )) # loop over the list of csv files for f in csv_files: # read the csv file df = pd.read_csv(f) # print the location and filename print ( 'Location:' , f) print ( 'File Name:' , f.split( "\\" )[ - 1 ]) # print the content print ( 'Content:' ) display(df) print () |
Output:
Note: The program reads all CSV files in the folder in which the program itself is present.
