用 0 天替换 NaT [英] replacing NaT with 0 days

问题描述

我有一个看起来撒谎的熊猫数据框:

I have a pandas dataframe that looks lie:

A      
3 days    
NaT       
4 days

有没有办法用0天替换NaT?

Is there a way to replace the NaT with 0 days ?

谢谢，埃德

推荐答案

请注意，其他答案不再是最新的.首选语法是:

Please note that the other answers are not up to date anymore. The preferred syntax is:

df['column'].fillna(pd.Timedelta(seconds=0))

前面提到的

df['column'].fillna(0)

将导致:

FutureWarning:不推荐将整数传递给 fillna，将引发未来版本中的类型错误.要保留旧行为，请通过pd.Timedelta(seconds=n) 代替.df['column'] = df['column'].fillna(0)

FutureWarning: Passing integers to fillna is deprecated, will raise a TypeError in a future version. To retain the old behavior, pass pd.Timedelta(seconds=n) instead. df['column'] = df['column'].fillna(0)
