DataFrame.equals : Check DataFrame equality. Examples --- This example shows comparing two DataFrames that are equal but with columns of differing dtypes. >>> from pandas.testing import assert_frame_equal >>> df1 =pd.DataFrame({'a': [1, 2], 'b': [3, 4]}) >>> df2 = pd.DataFrame...
The two columns x1 and x3 look similar, so let’s compare them in Python! Example 1: Check If All Elements in Two pandas DataFrame Columns are Equal In Example 1, I’ll illustrate how to test whether each element of a first column is equal to each element of a second column. ...
Dataframe 1: 2018 2019 2020 A 1 1 1 B 0 1 2 C 2 0 0 Dataframe 2: 2018 2019 2020 A 1 0 0 B 0 1 1 C 1 1 1 本质上,我尝试将以下函数应用于两个数据帧中具有相同索引和相同列的每一对单元格,然后将比较结果映射到相同位置的新数据帧: def compare_two(cell_1, cell_2): if cell_1...

To compare the performance difference between Pickle’s most compatible protocol and the default protocol, let’s first serialize a Pandas DataFrame using the default protocol. Note that this is the protocol version that Pickle uses if no specific protocol is explicitly stated: import pickle import ...
将各个DataFrame列绘制到单独的subplot中 sharex 如果subplots=True,则共用同一个X轴,包括刻度和界限 sharey 如果subplots=True,则共用同一个Y轴,包括刻度和界限 figsize 表示图像大小的元组 title 表示图像标题的字符串 legend 添加—个subplot图例(默认为True) sort_columns 以字母表顺序绘制各列,默认使用前列顺序 ...
