This note is created when I started to learn the Learn Python 3 on Codecademy.

Basic

  • Multiplines string
      leaves_of_grass = """
      Poets to come! orators, singers, musicians to come!
      Not to-day is to justify me and answer what I am for,
      But you, a new brood, native, athletic, continental, greater than
        before known,
      Arouse! for you must justify me.
      """
    
  • To pass variables to a function, there are 2 ways: positional arguments (1st value for the 1st arg,…) and keyword arguments (with the keywords)
  • We can define a default keyword like this
      def greet_customer(special_item, grocery_store="Engrossing Grocers"):
          print("Welcome to "+ grocery_store + ".")
          print("Our special is " + special_item + ".")
          print("Have fun shopping!")
    
  • Multiple return values
    def square_point(x_value, y_value):
    x_2 = x_value * x_value
    y_2 = y_value * y_value
    return x_2, y_2
