This algorithm would allow five numbers to be inputted and would work out the total. A count-controlled loop would be used because it is known, in advance, how many times the algorithm needs to loop.

(See “Flow control” below.) This isn’t wrong as such, but it misses the point of how Python works. A for loop in Python doesn’t require an index; it can just traverse the object to be ...

Condition-controlled loops have a condition ... If the condition is never met, then the program loops infinitely. Consider this simple algorithm to count up in twos from one to a hundred: the ...
