By the end of this unit, you should be comfortable selecting and dropping specific columns from a DataFrame. It might seem strange to discuss splitting a DataFrame in a course section on joining them, but we'll do so here to create the DataFrames that we'll join later on. We take this...
This might be a case of fixing symptoms however, we may need to take a harder look at aligning chunks and what that means in the context of non-series Columns. Fixes #21581.
由于Pandas 数据结构上的对象实例方法集通常是丰富且富有表现力的,因此我们通常只想在每个组上调用一个 DataFrame 函数。GroupBy 名称对于使用过基于 SQL 的工具(或itertools)的人来说应该非常熟悉,您可以在其中编写如下代码: SELECTColumn1,Column2,mean(Column3),sum(Column4)FROMSomeTableGROUPBYColumn1,Column2 ...

You can drop rows that have any missing values, drop any duplicate rows and build a pairplot of the DataFrame using seaborn in order to get a visual sense of the data. You'll color the data by the 'rating' column. Check out the plots and see what information you can get from them....
