在pandas 1.0 中,引入了一种新的转换方法.convert_dtypes。它会尝试将Series 换为支持 pd.NA 类型。以city_mpg 系列为例,它将把类型从int64转换为Int64: >>>city_mpg.convert_dtypes()01919223310417..41139194114020411411841142184114316Name: city08, Length:41144, dtype: Int64>>>city_mpg.astype('Int16')019...

The above code first creates a Pandas Series object s containing three strings that represent dates in 'month/day/year' format. r = pd.to_datetime(pd.Series(s)): This line uses the pd.to_datetime() method to convert each string date into a Pandas datetime object, and then create a ne...
