The best way to do this is to check all columns against the first column usingDataFrame.eq(). We will useiloc[]property for filtering the columns and then put this result intoDataFrame.eq(). The PandasDataFrame.eq()is a wrapper used for the comparison of the value. It provides a conven...

在这个方法中,为了计算给定的数据框架列的平均值,用户需要调用mean()函数,作为其参数,用户将使用[[]]并传递要计算平均值的数据框架列的名称,这将以r语言向用户返回提供的数据框架列的平均值。在这个例子中,我们将使用r语言中的[[]]的mean()函数来计算给定数据框架的第三列的平均数(与前面的例子相同)。
