I have a separate code file for the mean, median, and mode; I just need a new python code which will open or print the mean, median, and mode on a single python code. The data or numbers to compute the mean, median, and mode is in txt file named "numbers.txt" 

Just create a separate python file which will read the .txt file (numbers.txt) and will open my code in mean.py, median.py, and mode.py; then print them out. 

See my code for mean, median, and mode below; as well as the .txt file for your reference.
