Why Does Apply Change Dtype In Pandas Dataframe Columns

I have the following dataframe: import pandas as pd import numpy as np df = pd.DataFrame(dict(A = np.arange(3), B = np.random.randn(3),

Solution 1:

You can use parameter reduce=False and more info here:

print (df.apply(lambda x: x.dtype, reduce=False))

Aint32Bfloat64CobjectDdatetime64[ns]dtype: object

In newer versions of pandas is possible use:

print (df.apply(lambda x: x.dtype, result_type='expand'))
