更改 python 数据表中的列类型
change type of columns in python Datatable
是否可以在 python datatable 中将 stypes.int8
更改为 stypes.int32
?
As the name suggests, the package is closely related to R's data.table and attempts to mimic its core algorithms and API.
因此,您可以按照此 link
and 进行数据类型转换。
你可以轻松做到:
假设你有一个 DT 并且字段类型是 int32
DT = dt.Frame({'x': [1,2,3,4,5]})
并且我们希望将其类型从 int32 更改为 int8 as
DT['x'] = dt.int8
语法如下:
DT['column'] = datatype # (dt.int32 or dt.str32 etc etcc)
