Aloopis a sequence of instructions that is continually repeated until a certain condition is reached. For instance, we have a collection of items and we create a loop to go through all elements of the collection. Loops in Python can be created withfororwhilestatements. Python for statement Py...
The break and continue statements are used to alter the flow of loops. The break Statement The break statement terminates the for loop immediately before it loops through all the items. For example, languages = ['Swift', 'Python', 'Go', 'C++'] for lang in languages: if lang == 'Go'...
