chop_threshold : float or None if set to a float value, all float values smaller then the given threshold will be displayed as exactly 0 by repr and friends. [default: None] [currently: None] display.colheader_justify : 'left'/'right' Controls the justification of column headers. used ...
To count unique values in the Pandas DataFrame column use theSeries.unique()function along with the size attribute. Theseries.unique()function returns all unique values from a column by removing duplicate values and the size attribute returns a count of unique values in a column of DataFrame. S...
