# find maximum value of a # single column 'x' maxClm=df.max()['x'] 结果将与上述相同。输出: 也可以传递列列表而不是单个列来查找指定列的最大值 Python3实现 # find maximum values of a list of columns maxValues=df[['x','z']].max() print("Maximum value in column 'x' & 'z': ...
Row where col2 has maximum value: 3 Row where col3 has maximum value: 2 Explanation: The above code creates a pandas DataFrame 'df' with three columns - 'col1', 'col2', and 'col3'. The code then uses the 'argmax()' function to find the index of the maximum value in each colu...

如上所述,get_option()和set_option()可从 pandas 命名空间中调用。要更改选项,请调用set_option('option regex', new_value)。 In [12]: pd.get_option("mode.sim_interactive")Out[12]: FalseIn [13]: pd.set_option("mode.sim_interactive", True)In [14]: pd.get_option("mode.sim_interactive...
