import os import glob import pandas as pd os.chdir("/uploads") extension = 'csv' all_filenames = [i for i in glob.glob('*.{}'.format(extension))] #combine all files in the list combined_csv = pd.concat([pd.read_csv(f) for f in all_filenames ]) #export to csv combined_csv.to_csv( "combined_csv.csv", index=False, encoding='utf-8-sig') |
Before executing the python script you need to create the directory called as uploads where you will put all the input csv files which needs to be merged like this
Now you execute the python script by typing the below command as shown below
