#Lists

  • Lists are a sequence of variables, we can use them to store multiple items to one, collections of data, a d are changeable and allow for duplicates
  • Tuple: collection that is ordered, unchangeable, allows duplicates
  • Set: collection that is unordered, unchangeable, doesn’t allow duplicates
  • Dictionary: collection that is ordered, changeable, doesn’t allow duplicates

Terms

  • Index: a term used to sort data in order to reference to an element in a list (allows for duplicates)
  • Elements: the values in the list assigned to an index

  • Append(), adds data to end

  • Index() returns the index of the first element with specified value

  • Insert() adds a value into given position

  • Remove() removes the first item with specified value

  • Iteration saves time!

  • Iteration is the repetition of a process or utterance applied to the result or taken from a previous statement.
  • There’s a lot of types of iteration though, what to use? How do we apply iteration to lists?

  • Some methods include using a “for loop”, using a “for loop and range()”, using a “while loop”, and using comprehension
