# The print function

print('Hello') # Hello

print(3) # 3

# Variables

greeting = 'Hello'

G-Goldstein

# Challenge one: What does this function do? How do you use it?

def welcome(name):
	return 'Hello ' + name

# Solution:

### When called and a name passed, this function returns a greeting string for that name. Importantly, this function doesn't print anything to the console, it just creates a string that we can then print later, or do other things with.

person = 'Graham'

# Lists

numbers = [3, 5, 7, 4, 2]

## Don't worry about remembering the syntax, as long as you can refer back to an example.

print(numbers)

print(max(numbers))

-- Begin lines with two dashes to have the SQL engine ignore them. Great for comments or for storing an old line of code that you might want to use again later.

-- IBM i command STRSQL enters interactive SQL, from which you can run SQL statements.

-- The SOFPACK table stores information about software packages.

-- In SQL, use SELECT to query tables.
-- The * here is a wildcard meaning all columns.

Terminology

A Docker image is a template for an application, together with its dependencies, runtime environment and metadata.

A Docker container is a running instance of a Docker image.

Commands

Use command docker alone to see Docker usage. You may need root access.

Main process, and container lifecycle

https://hub.docker.com/_/busybox

For busybox, the default execution is sh. So, after using run, we find ourselves in a shell environment:

docker run -it busybox

But we can specify an alternate command to run in the busybox container by appending it to the Docker run command:
