在日期框架中,我有“日期”列,如果日期> CurrentDate(datetime.now())将状态更新为“过期”,如果日期Date Status
2019-06-28 SW Expires 2018-Q2
2020-01-20 SW Expires 2018-Q1
2018-07-18 SW Expired
X Current
Y Current
2019-06-20 Current
df['Qtr'] = pd.to_datetime(df['Date']).dt.quarter
df['Qtr']=pd.PeriodIndex(pd.to_datetime(df['Date']), freq='Q')
df['Qtr']=df['Qtr'].astype(str)
df['Qtr']="SW Expires"+' '+df['Qtr']
df['Status'] = df['Date'].apply (lambda x : 'SW Expired' if x >
CurrentDate else(Midrange_SWProduct['Qtr'] x < CurrentDate else('current'
Midrange_SWProduct['Qtr'] x == CurrentDate or 'X' or 'Y' else NA )))
答案 0 :(得分:0)
最好的方法是两次编写自定义函数和调用Apply函数。
def custom_funct(row):
do anthing
df['res']=df.apply(lambda row: custom_funct(row),axis=1)
