使用pandas检查值存在于哪一列

import pandas as pd

data = pd.read_csv("data.csv")  # 替换为你的数据文件路径

value = "your_value"  # 替换为你要检查的值
columns_with_value = []
for column in data.columns:
    if value in data[column].values:
        columns_with_value.append(column)

print("值", value, "存在于以下列中：")
for column in columns_with_value:
    print(column)
