I am having issues with it just printing out the min and max value. It gives this to me instead.
Choose an option:
1. Load data
2. Display computed statistics
3. Save computed statistics
4. Exit
Choice:2
Below are the computed values:
Min = ['87', ' 63', ' 100', ' 94', ' 56', ' 77', ' 60', ' 72', ' 99', ' 83']
Max = ['87', ' 63', ' 100', ' 94', ' 56', ' 77', ' 60', ' 72', ' 99', ' 83']
Choose an option:
I also have to add in mean and median but cannot seem to find the right modules that I need to call so they work.
I have tried both import statistics and import math.
I am on python 3.

they are few ways...
if me i'll convert each item in line.strip().split(',') to integer 1st, then add into data_list. pretty sure min/median formula are short/simple to code, u dont need to import any modules for that, its up to u anyway

data_list = []
with open('stats.txt', 'r') as f:
    for line in f:
        for number in line.strip().split(','):     #line  changed
            data_list+=[int(number)]               #line  changed
    data_list.sort()
return (data_list)
