如何将datacompy.compare.report输出到文本或csv文件？我只能在终端里看到它，需要一个文件

import datacompy

# 创建比较对象
compare = datacompy.Compare(df1, df2, join_columns=['id'])

# 生成报告
report = compare.report()

# 将报告输出到文本文件
with open('report.txt', 'w') as file:
    file.write(report)

import csv
import datacompy

# 创建比较对象
compare = datacompy.Compare(df1, df2, join_columns=['id'])

# 生成报告
report = compare.report()

# 将报告输出到CSV文件
with open('report.csv', 'w', newline='') as file:
    writer = csv.writer(file)
    writer.writerow([report])
