如何将函数返回的元组追加到python中的dataframe？

import pandas as pd

def my_function():
    # 执行一些操作
    return (value1, value2, value3)

result = my_function()

df = pd.DataFrame(columns=['Column1', 'Column2', 'Column3'])

df.loc[len(df)] = result

import pandas as pd

def my_function():
    # 执行一些操作
    return (value1, value2, value3)

result = my_function()

df = pd.DataFrame(columns=['Column1', 'Column2', 'Column3'])
df.loc[len(df)] = result
