Currently, str.get_dummies() sets the default dtype to np.int64 in the following locations. These can be updated to use np.bool_ for consistency: pandas/pandas/core/strings/object_array.py ( _str_get_dummies() ) pandas/pandas/core/arrays/string_arrow.py ( _str_get_dummies() ) pandas...
A int64 B float64 C bool D object dtype: object 'infer_obejects'可能看起来微不足道,但在有很多列时作用巨大。 15. Memory_usage Memory_usage()返回每列使用的内存量(以字节为单位)。考虑下面的数据,其中每一列有一百万行。 df_large = pd.DataFrame({'A': np.random.randn(1000000), 'B': np...

to_numeric()will give us either anint64orfloat64dtype by default. We can use an option to cast to eitherinteger,signed,unsignedorfloat: # python 3.ximportpandasaspd s=pd.Series([-3,1,-5])print(s)print(pd.to_numeric(s,downcast="integer")) ...
to_numeric() gibt uns standardmäßig entweder einen int64 oder float64 dtype. Wir können eine Option verwenden, um entweder auf integer, signed, unsigned oder float zu casten:# python 3.x import pandas as pd s = pd.Series([-3, 1, -5]) print(s) print(pd.to_numeric(s, ...
