答案:A.mean() 解析: A. mean(): 这是正确答案。DataFrame对象的mean()方法用于计算列的平均值。 B. average(): 这是错误的选项。虽然Pandas中的Series对象有average()方法用于计算加权平均值,但是DataFrame对象没有这个方法。 C. median(): 这是错误的选项。median()方法用于计算列的中位数,而不是平...
To get column average or mean from pandas DataFrame use eithermean()ordescribe()method. Themean()method is used to return the mean of the values along the specified axis. If you apply this method on a series object, it returns a scalar value, which is the mean value of all the observa...

print(data.groupby('group1').mean()) # Get mean by group # x1 x2 # group1 # A 5.666667 14.0 # B 3.500000 14.5 # C 4.666667 15.0The previous console output shows the result of our Python syntax. You can see the averages for each group and column in our pandas DataFrame....
The method returns aDataFramethat has a new level of column labels whose innermost level consists of the pivoted index labels. #Pandas: Calculate median across multiple DataFrames If you need to find the median across the two DataFrames, use theDataFrame.medianmethod instead. ...
In this output, therolling_triangleDataFrame contains the triangular weighted rolling mean for each column. Note that the first row will have NaN values due to the insufficient number of data points for the specified window size. Adjust the window size and other parameters based on your specific...
