Access a group of rows and columns by label(s) or a boolean Series. Unlike pandas, the index order is not preserved in the result. Purely integer-location based indexing for selection by position. This is useful when the index needs to be treated as a column, or when the index is meaningless and needs to be reset to the default before another operation.Series¶ Check whether all characters in each string are whitespaces. skipna : bool, default True Exclude NA/null values when computing the result.value_counts (normalize: bool = False, sort: bool = True, ascending: bool = False, bins: None = None, dropna: bool = True) → Series¶ Return a Series containing counts of unique values.
