DOC: Fix flake8 issue in whatsnew files #24177
Description
In some of the whatsnew files we are using implicit imports. For example in "whatsnew/v0.11.0.rst"
we import pandas from pandas import * implicitly. We instantiate using the implicitly imported class DataFrame later in the code.
df1 = DataFrame(randn(8, 1), columns = ['A'], dtype = 'float32')
df1
The preferred approach is to use explicit import as import pandas as pd and replace the call to DataFrame with pd.DateFrame.
Note:
import pandas as pdis part of the header, so it is imported by default. In that case just replacingDataFramewithpd.DateFrameand removingfrom pandas import *should be enough.- Many whatnew files are using the preferred approach of explicit calling
pd.*. However, the import statement offrom pandas import *is included by default. In such case, just remove the import statement.
