Concatenate several csv into one [closed]

I have the following code to concatenate several csvs in one only separating each one by a blank row in the final csv. But he is only able to catch the first csv without repeating the same action with the rest. Any idea how I could solve it? Thanks in advance.

#!/usr/bin/env python


    import pandas as pd
    import glob, os
    import shutil

    #import csv files from folder
    path = r'/Users/sonia/Animalsmanage/output'
    allFiles = glob.glob(path + "/*.csv")

    with open('finaloutput.csv', 'wb') as outfile:
        for i, fname in enumerate(allFiles):
            with open(fname, 'rb') as infile:
                if i != 0:
                    infile.readline()
                    outfile.write(bytearray('\n'))  
                shutil.copyfileobj(infile, outfile)
                print(fname + " has been imported.")
