Merge CSVs in Python

mergeCsvs.py

# Merge CSV files from a folder and save a new merged csv file
import os            # Handle directories
import pandas as pd  # Handle dataframes
import time          # Get datetime

csvsDirectory = 'csvs'
outputMergedDirectory = 'csvs'
mergedFilename = 'merged.csv'

fileList = [csvFile for csvFile in os.listdir(csvsDirectory) if csvFile.endswith(".csv")]

# merge all csv files
rows = []
for csv in fileList:
    if csv == 'merged.csv':
        continue

    df = pd.read_csv(os.path.join(csvsDirectory, csv), index_col=None, header=0, encoding='latin1')
    rows.append(df)
    os.remove(os.path.join(csvsDirectory, csv))

bulkDF = pd.read_csv(os.path.join(csvsDirectory, mergedFilename), encoding='latin1')
merged = pd.concat(rows, axis=0, ignore_index=True)
merged = pd.concat([bulkDF, merged])
merged.to_csv(os.path.join(outputMergedDirectory, mergedFilename), index=False)

can I merge several CSV files without using glob or pandas libraries ?
only using os

@sireenx, no pandas, pure python: https://gist.github.com/fitoprincipe/67df15dfc7f57adb96c1c1de79ef210f
