如何让dataframe中两列时间相减？

Question

Answer 1

两个字段类型不匹配不能进行运算
运算之前先转换一下类型

df['age'] = pd.to_datetime(df['indate']) - pd.to_datetime(df['dob'])

Answer 2

import numpy as np
import matplotlib.pyplot as plt
import pandas as pd
print(pd.read_csv('002340.csv'))
df=pd.read_csv('002340.csv',usecols=[5,2],delimiter=',')
print(df)
print(df.close-df.open)

重点在DataFrame.列名-DataFrame.列名
