Python数据框：日期列重新格式化为“ NaTType不支持strftime”错误

Question

I'm trying to reformat the following column names. They all have been converted to datetime columns already.

The code works for the first 3 columns in my list. However, the last two columns breaks it.

date_columns = ['DTI', 'DTO', 'DTD', 'DTE', 'DTINS']

for i in date_columns:
    df_EVENT5_13[i] = df_EVENT5_13[i].apply(lambda x:x.date().strftime('%m/%d/%Y'))

Below is the error I get:

ValueError: NaTType does not support strftime

Answer 1

尝试df_EVENT5_13 [i] = df_EVENT5_13 [i] .dt.date
