isnull() in pandas not able to identify blank value (Python coding)
#1
import pandas as pd
t1=pd.DataFrame()
t1 ['name'] = ["dp","ag","wp"]
t1['status'] = ['a','b','c']
t1['age'] = [10,"",15]
t1
##
print(t1.isnull().values)
Why is the execution of this node not able to identify blank (see "age" column, 2nd row). isnull() is coming false for all the cells, see below output Output:
Output:
[[False False False] [False False False] [False False False]]

I didn't see in the official docs that .isnull should handle such cases.
if you want to catch empty strings, just do df == "".
