Python:合并2个分隔不同的csv文件的有效方法

import csv

def read_csv(file_path):
    data = []
    with open(file_path, 'r') as file:
        reader = csv.reader(file)
        for row in reader:
            data.append(row)
    return data

def merge_csv(file1, file2):
    data1 = read_csv(file1)
    data2 = read_csv(file2)
    merged_data = data1 + data2
    return merged_data

def write_csv(file_path, data):
    with open(file_path, 'w', newline='') as file:
        writer = csv.writer(file)
        writer.writerows(data)

file1 = 'file1.csv'
file2 = 'file2.csv'
merged_data = merge_csv(file1, file2)
output_file = 'merged.csv'
write_csv(output_file, merged_data)
