print("Hello, World!")Hello, World!Hello World
Any programmer knows, the first test to show if you know a language it printing Hello, World!
This interactive notebook uses only pure Python, no external resources to get started.
Topics covered:
- Hello World
- Types (int, float, str, bool, list, dict, set, tuple)
- Variables & assignment
- Operators (arithmetic, comparison, logical)
There are two parts to the syntax above: - print is a builtin function - “Hello, World!” is a string
When print is given a single, string argument like above, it displays that input.
Next, give yourself a little praise, you’re on your way to mastering Python and more.
Set up two variables to work with: - compliment - name
compliment = "Great work"name = "Your name here"print(compliment)
print(name)Great work
Your name hereWorking with Variables
Variables are essential to programming. A variable creates a named container for information.
Variable names can only contain letters, digits, and underscores, must start with a letter or underscore, and can’t be a reserved word (e.g., if, def, return).
In Python, use = to assign values: x = 5.
Creating and working with variables makes programming much easier!
It creates a reusable, custom name.
print(compliment)
print(name)Great work
Your name hereSomething about the above looks off…
It should be on one line.
compliment_and_name = compliment + nameprint(compliment_and_name)Great workYour name hereStill not quite right…
compliment_and_name_2 = compliment +', '+ nameprint(compliment_and_name_2)Great work, Your name hereWith feeling!
compliment_and_name_3 = compliment_and_name_2 +'!'print(compliment_and_name_3)Great work, Your name here!
