In this tutorial, we will discuss how we can compute the average of the list in Python.If true, it should return the index of 4 "(0,0)". in the following matrix, it should check if 4 > average(4,1,5). I want to find the indices of all elements of a 2D array that are greater than the average of the column values.Since the csv file you have will be a "row-major" list-of-lists, what data structure would you use to store one number (the total) for each column?. Once you have the csv file as a list-of-lists, remember that to calculate the mean of a column, you need to calculate the sum of each column.If we open the csv we note that the csv table contains the field Value as heading of all columns.

Now we save the pivot table to csv by using the function to_csv() applied to the dataframe.With the has_header method of Sniffer, we can check if the first row contains column headers. The csv class in Python has a Sniffer class to deduce the format of a CSV.

There are 4 rows in this CSV however, there may be a header row (displaying field names) so we shouldn't count this row in our calculation for the count of bike rides.

I managed to read the csv file: from numpy import genfromtxt emp_code = genfromtxt('C:\\Users\\V\\Desktop\\data science\\

I am trying to find the average of a column in this csv file.
