推荐答案

您的错误是第2行.df['intage'] = int(df['age'])无效，您无法将pandas系列传递给int函数.

Your error is line 2. df['intage'] = int(df['age']) is not valid, you can't pass a pandas series to the int function.

如果df ['age']是对象dtype，则需要使用astype.

You need to use astype if df['age'] is object dtype.

df['intage'] = df['age'].astype(int)

或者因为要减去两个日期，所以需要使用带days属性的dt访问器来获取天数为整数

Or since you are subtracting two dates, you need to use dt accessor with the days attribute to get the number of days as an integer

df['intage'] = df['age'].dt.days
