如何编写两本词典到CSV？

import csv

# 准备数据
dictionary1 = {
    "apple": "a fruit",
    "car": "a vehicle",
    "house": "a place to live"
}

dictionary2 = {
    "cat": "a pet",
    "dog": "another pet",
    "tree": "a plant"
}

# 创建CSV文件
csv_file1 = open("dictionary1.csv", "w", newline="")
csv_file2 = open("dictionary2.csv", "w", newline="")
writer1 = csv.writer(csv_file1)
writer2 = csv.writer(csv_file2)

# 写入数据
for word, definition in dictionary1.items():
    writer1.writerow([word, definition])

for word, definition in dictionary2.items():
    writer2.writerow([word, definition])

# 关闭文件
csv_file1.close()
csv_file2.close()
