- accumulator pattern
A pattern where the program initializes an accumulator variable and then changes it during each iteration, accumulating a final result.
- Control Flow
Also known as the flow of execution, the order in which a program executes. By default, the control flow is *sequential*.
- for loop traversal (
Traversing a string or a list means accessing each character in the string or item in the list, one at a time. For example, the following for loop:
for ix in 'Example': ...
executes the body of the loop 7 times with different values of
A variable or value used to select a member of an ordered collection, such as a character from a string, or an element from a list.
- loop body
The loop body contains the statements of the program that will be iterate through upon each loop. The loop body is always indented.
A sequence of statements, or a style of coding something that has general applicability in a number of different situations. Part of becoming a mature programmer is to learn and establish the patterns and algorithms that form your toolkit.
A function that produces a list of numbers. For example,
range(5), produces a list of five numbers, starting with 0,
[0, 1, 2, 3, 4].
- sequential flow
The execution of a program from top to bottom, one statement at a time
- terminating condition
A condition which stops an interation from continuing
To iterate through the elements of a collection, performing a similar operation on each.
