- list:
- A sequence of values.
- element:
- One of the values in a list (or other sequence), also called items.
- index:
- An integer value that indicates an element in a list.
- nested list:
- A list that is an element of another list.
- list traversal:
- The sequential accessing of each element in a list.
- mapping:
- A relationship in which each element of one set corresponds to an element of another set. For example, a list is a mapping from indices to elements.
- accumulator:
- A variable used in a loop to add up or accumulate a result.
- augmented assignment:
- A statement that updates the value of a variable using an operator like
+=. - reduce:
- A processing pattern that traverses a sequence and accumulates the elements into a single result.
- map:
- A processing pattern that traverses a sequence and performs an operation on each element.
- filter:
- A processing pattern that traverses a list and selects the elements that satisfy some criterion.
- object:
- Something a variable can refer to. An object has a type and a value.
- equivalent:
- Having the same value.
- identical:
- Being the same object (which implies equivalence).
- reference:
- The association between a variable and its value.
- aliasing:
- A circumstance where two or more variables refer to the same object.
- delimiter:
- A character or string used to indicate where a string should be split.
