Since keys must be unique, duplicates are automatically removed. By converting the dictionary back to a list using list(), we obtain our unique values while preserving their order. This method is not only concise but also leverages the efficiency of dictionaries in Python. Using the pandas ...

pandas.unique(values) Let’s see an example. Since the unique() function takes values, you need to get the value of a column usingdf[columns_list].values.ravel(). # Using pandas.unique() to unique values in multiple columns df2 = pd.unique(df[['Courses', 'Fee']].values.ravel())...
DataFrame.get_values(self)[source] 将稀疏值转换为稠密值后,返回一个ndarray。 从0.25.0版开始不推荐使用:np.asarray(..)或DataFrame.values()代替。 这与.values非稀疏数据相同。对于SparseArray中包含的稀疏数据,首先将其转换为密集表示。 返回值:
