- object:
- Something a variable can refer to. For now, you can use “object” and “value” interchangeably.
- sequence:
- An ordered set; that is, a set of values where each value is identified by an integer index.
- item:
- One of the values in a sequence.
- index:
- An integer value used to select an item in a sequence, such as a character in a string.
- slice:
- A part of a string specified by a range of indices.
- empty string:
- A string with no characters and length 0, represented by two quotation marks.
- immutable:
- The property of a sequence whose items cannot be assigned.
- traverse:
- To iterate through the items in a sequence, performing a similar operation on each.
- search:
- A pattern of traversal that stops when it finds what it is looking for.
- counter:
- A variable used to count something, usually initialized to zero and then incremented.
- method:
- A function that is associated with an object and called using dot notation.
- invocation:
