如何从 Python 中的数据框的日期和生日获取年龄列表？

您必须使用应用 -

test = [
    ['8/17/2008', ['2005', '2004']],
    ['8/15/2008', ['2007', '2006']]
]

dataframe = pd.DataFrame(test, columns=['date', 'year'])
dataframe['date'] = pd.to_datetime(dataframe['date'])

def calculate_year(row):
    age = []
    for year in row['year']:
        age.append(row['date'].year - int(year))
    return age

dataframe['age'] = dataframe.apply(calculate_year, axis=1)

要么

dataframe['age'] = dataframe.apply(lambda row: [
    row['date'].year - int(year)
    for year in row['year']
], axis=1)
