Counter.: A variable used to count something. It’s usually initialized to zero and then incremented.
Empty String.: A string with no characters and length 0, represented by two quotation marks.
Format Operator.: An operator, %, that takes a format string and a tuple and generates a string that includes the elements of the tuple formatted as specified by the format string.
Format Sequence.: A sequence of characters in a format string, like %d, that specifies how a value should be formatted.
Format String.: A string, used with the format operator, that contains format sequences.
Flag.: A boolean variable used to indicate whether a condition is true or false.
Invocation.: A statement that calls a method.
Immutable.: A property of sequences whose items cannot be reassigned.
String Index.: An integer value used to select a character in a string.
Item.: One of the values in a sequence.
Method.: A function that is associated with an object and called using dot notation.
String Object.: A string that a variable can refer to. For now, you can use “object” and “value” interchangeably.
Search.: A pattern of traversal that stops when it finds what it is looking for.
Sequence.: An ordered set; that is, a set of values where each value is identified by an integer index.
Slice.: A part of a string specified by a range of indicies.
Traverse.: To iterate through the items in a sequence, performing a similar operation on each.
