print ("""\n - PRACTICE AND SHORT SUMMARY OF LISTS - This is a practice of lists in which I try to make at the same time a short summary of it. It is not completed professionally and is not an exact guide of lists in Python, however it points main commands used on it. Sometimes this code exceed the time limit of loading, so please, be patient and try to run again. This code is not finished yet. I will do while I am learning about lists. Lists are hard for me, so if you have any feedback, please, write it in comments. It will help me to have more viewpoints and learn more. Please, read the conclusions and shares your opinion.
