Web Reference: On a tangential note, it's common for a dataframe to have a literal string 'NaN' instead of an actual NaN value. To make sure that a dataframe indeed has NaN values, check with df.isna().any(). Replace all NaN elements in column ‘A’, ‘B’, ‘C’, and ‘D’, with 0, 1, 2, and 3 respectively. Only replace the first NaN element. When filling using a DataFrame, replacement happens along the same column names and same indices. Note that column D is not affected since it is not present in df2.
