如何比较具有算术条件的两个CSV文件中的字段？

import csv

def compare_csv_fields(csv_file1, csv_file2, field_name, condition):
    with open(csv_file1, 'r') as file1, open(csv_file2, 'r') as file2:
        csv_reader1 = csv.DictReader(file1)
        csv_reader2 = csv.DictReader(file2)
        
        for row1, row2 in zip(csv_reader1, csv_reader2):
            value1 = float(row1[field_name])
            value2 = float(row2[field_name])
            
            if eval(f"{value1} {condition} {value2}"):
                print(f"Field '{field_name}' in CSV file 1 ({csv_file1}) is {condition} Field '{field_name}' in CSV file 2 ({csv_file2})")
                print(f"Value in CSV file 1: {value1}")
                print(f"Value in CSV file 2: {value2}")
                print("---")

# 示例用法
compare_csv_fields('file1.csv', 'file2.csv', 'price', '>=')
