Check if single cell value is NaN in Pandas

Question

I just want to check if a single cell in Pandas series is null or not i.e. to check if a value is NaN.

All other answers are for series and arrays, but not for single value.

I have tried pandas.notnull, pandas.isnull, numpy.isnan. Is there a solution for a single value only?

Answer 1

Try this:

import pandas as pd import numpy as np from pandas import *  >>> L = [4, nan ,6] >>> df = Series(L)  >>> df 0     4 1   NaN 2     6  >>> if(pd.isnull(df[1])):         print "Found"  Found  >>> if(np.isnan(df[1])):         print "Found"  Found
