I would like to write a uproot script in python to get the bin content in all bins(boxes) in a 2D histogram and add it to a vector and then print it to a .txt file with bin size on x and y axis as first line and then bin content value line-by-line i.e. rows and then columns.
Is this possible to do with uproot package on python function that takes the root file and the histogram name as input.
Essentially, I would like to know how to get bin content of all bins along x and y axis of a 2D histograms. What functions to use in uproot ?
