How can I combine them together in 1 single Csv file? Note: I do not want to specific which column to combine, I just want the new data to be combine with the first csv file. I had tried to combine them but the new added value is showing at the bottom instead beside it.

My code

import os
import glob
import pandas as pd
os.chdir("C:/Users/crayx/PycharmProjects/xxx/Csv")

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')

Expected Output:

Answer

Create a new column in the original dataframe with the content of the column of the second dataframe. Something like this:

my_csvs = [pd.read_csv(f) for f in all_filenames]
my_csv = my_csvs[0]
for csv in my_csvs[1:]:
    for column in csv.columns:
        my_csv[column] = csv[column]
