Intro to coding

• Functions are named chunks of code that somebody else wrote
• They are “tools” for you to use.
• print is a function (“tool”) that you can use to make text appear on the screen.
  • print("Hello, World")
• Variables are named “boxes” that hold values.
  • x = 7
  • print(x)
• Variables can be repeatedly re-assigned:
  • x = 17
  • print(x)
• Variables and numbers can be used in expressions:
  • y = x + 5
  • print(y)
• You can interpolate values into strings using f""
  • print("The variable x currently holds the value {x}")
• Try it out!!!
