Here's a very simple procedure to move your Python script from local to EC2 Instance and run it.

> 1. scp -i   ec2-user@.compute-1.amazonaws.com: your file to be>
> 2. Cd to to the directory in EC2 containing the file. Type Python  There it executed.

Here's a concrete examples for those who likes things shown step-by-step:

1. In your local directory, create a python script with the following code: print("Hello AWS")
2. Assuming you already have AWS already set up and you want to run this script in EC2, you need to SCP (Secure Copy Protocol) your file to a directory in EC2. So here's an example:

- My filepath to pem is ~/Desktop/random.pem.
- My filepath to py file is ~/Desktop/hello_aws.py
- My public DNS is ec22-34-12-888
- The ec2 directory where I want my script to be is in /home/ec2-user
- So the full command I run in my local terminal is:

scp -i ~/Desktop/random.pem ~/Desktop/hello_aws.py ec2-user@ec2-34-201-49-170.compute-1.amazonaws.com:/home/ec2-user

3. Now ssh to your ec2 instance, cd to /home/ec2-user (Or wherever you put your file) and Python hello_aws.py
