import pandas as pd
import json
import ast  # Python 的 ast.literal_eval 可以安全解析 Python 字典字符串

df = pd.read_csv("alpha_list.csv", nrows=5)

# 方法1：用 ast.literal_eval（推荐，能解析 Python 字面量）
for i, row in df.iterrows():
    regular_str = row['regular']
    if pd.notna(regular_str):
        try:
            regular_dict = ast.literal_eval(regular_str)
            code = regular_dict.get('code', '')
            print(f"Row {i}: {code[:80]}...")
        except Exception as e:
            print(f"Row {i}: 解析失败 - {e}")

# 方法2：看看原始字符串前200个字符
print("\n原始字符串示例:")
print(df.iloc[0]['regular'][:200])
