![]() In Python, loops can be used to solve awesome and complex problems. These two types of loops can be used inside each other to generate nested loops(more on this later). Is an iterator based loop, which steps through the items of iterable objects like lists, tuples, string and executes a piece of code repeatedly for a number of times, based on the number of items in that iterable object.Įxecutes a block of statements repeatedly as long as the condition is TRUE. It only breaks out of the loop or stops executing the code block if the condition is FALSE, and in this case, the program will continue execution sequentially. Flowchart of a Loop Statementīased on the above diagram, a Python program will start at Start, and the execution will proceed to the condition statement, if the condition is TRUE, then the program will execute the code block.Įxecution will proceed again to the condition statement and the same process continues each time when the condition is TRUE. Given below is a flowchart that illustrates how a loop statement works. Thanks to loop statements, we can do just that. However, there will be cases where we may want a block of code to execute several times until a condition is met. if our code is made up of several lines of code, then execution will start at the first line, followed by the second, and so on. ![]() ![]() In Python, statements are executed in a sequential manner i.e. Example – Accumulate Numbers Until A Threshold Is Met.Example – Find A Fibonacci Sequence Upto nth Term Using The While Loop.Example – Find Word Count In A Text Using The for Loop.
