You had X points should be out of the loop

String methods can be used to change a string: .lower, .upper, .title etc

Difference between .choice and .choices in the random module

In every if statement that has an elif statement there must be an else statement

Someone used a function and did not return anything in the function and he's trying to use a variable that's inside the function outside.

Writing a neat code

Sample mean and Population mean

Getting user input.: int, float, eva and getting texts from user.

Node.js Deployment

Steps to deploy a Node.js app to DigitalOcean using PM2, NGINX as a reverse proxy and an SSL from LetsEncrypt

1. Sign up for Digital Ocean

If you use the referal link below, you get $10 free (1 or 2 months) https://m.do.co/c/5424d440c63a

2. Create a droplet and log in via ssh

I will be using the root user, but would suggest creating a new user
