Import os 

Import pandas as pd 

Import glob as gb

2nd step use glob library to match the patterns of csv files

Extension=”csv”

All_csv= [file for file in gb.gb (“*. {}.format (extension))]

3rd Step combined file in list as csv

all_csv = pd.concat ([pd.read_csv (file) for file in All_csv])

#export to csv

all_csv.to_csv (“all_csv.csv”, index=False, encoding=’utf-8-sig’)

Method#2 Terminal 

1st step check the working directory (where are you at the moment) by printing working directory

Pwd

2nd step Navigate to directory path here cd command is used to change directory

cd desktop/filesmerge

3rd step merged the files (cat is the command to create a file)

Cat*.csv>merged_file.csv
