将字符串列表搜索到panda dataframe中，并返回包含该字符串的整行，以构建新的csv文件

import pandas as pd

df = pd.read_csv('原始文件.csv')

search_results = pd.DataFrame(columns=df.columns)

search_strings = ['字符串1', '字符串2', '字符串3']

for index, row in df.iterrows():
    for search_string in search_strings:
        if search_string in row.values:
            search_results = search_results.append(row, ignore_index=True)
            break

search_results.to_csv('搜索结果.csv', index=False)
