_I am analysing one data set, which has four columns(attributes), I am able to access three columns, and getting the data as expected by df[‘name_of__column’]
but for another column when I try to access the data using the same command mentioned above, I am not able to get any data, instead I am getting an keyerror
whats special about that column which I am not able to get access to is:-
some block contain only one value, some contain multiple values(separated by ; ), and most of them under the same column has no value(NaN)
What could be the issue, due to which I am not able to get access of that column?
