The For Loop. In Python a for-loop is used to step through a sequence e.g., count through a series of numbers or step through the lines in a file. Syntax: for <name of loop control> in <something that can be iterated>: body. Program name: total = 0. for i in range (1, 4, 1): Initialize control. Check condition.

Python ‘for’ loop works well for a collection of known items. That is, we know the count, or we know the list of items. But what if we don’t know the count, or the list, rather we only know the condition to repeat (or not to repeat) the steps? For example, we want to repeat adding to a sum as long as the user input is a positive number. 6.
