Submit one python file with all of your problems. You must use the function names and inputs specified in the problem so that your code will work for any set of inputs. Be sure to include comments in the code to document what is happening. You may find it useful to write out pseudo code first, and then go back in and fill in the actual code, leaving the pseudo code as your comments. Anytime you have to print out something, be sure it is clearly labeled. So instead of printing just the number 3, print something descriptive like "The length of the input list is 3" Write a function with the definition author() that returns your auburn username (ex: emg0039) You are given three data files (data1.txt, data2.txt, and data3.txt) consisting of integers (1 integer on each line). Write Python code that reads each of these three files, computes sample mean and standard deviation for each data set and write them on a file, lastNameOutput.txt (using your own last name). For this problem, you should import simple_ds.py and use the mean function rather than including the code directly in your script. 1. 2. Next, combine the data of the three data sets in these data files and draw a histogram as well as print the result (combined data) on the screen. The output to the screen must be in a reader- friendly format. Use matplotlib to plot a histogram of the combined data and not matlab. Save the plot as last Name Histogram.png (using your own last name). Your function definition should be threeFileHistogram(file1, file2, file3)
