how-to-parse-date-column-in-pandas.py

df

df

Pandas DataFrame showing date column as string type

它被列为 object：

pandas_show_date_column.py

df["date"]

df["date"]

Pandas date column listed as object dtype before parsing 像这样解析它：

pandas_to_datetime.py

df["date"] = pd.to_datetime(df["date"])

df["date"] = pd.to_datetime(df["date"])

之后它将被列为 datetime64[ns]：

pandas_show_date_after.py

df["date"]

df["date"]

Pandas date column parsed as datetime64 ns type after pd.to_datetime
