Mentioned iterators have to say iterator protocol, an iterator protocol means that an object must provide a __next__ () method that either returns the next item in the iteration or throws an Stopiteration exception (equivalent to the meaning of an error) to terminate the iteration. The object that follows this protocol, however, is called an iterative object , also known as an iterator. In Python, theobject for a For

So naturally, when judging whether a condition is true, try to rely on the implicit "truth" in

Like most other languages, Python also has a for loop. The only reason you haven't seen them yet is that Python is doing well in many other ways, And you usually don't need them. Most other languages do not have the list data type as powerful as Python, so you need to do a l

nested structure" – Zen of Python To avoid a for loop, you can use these tools 1. List parsing/builder expressions To see a simple example, this example compiles a new sequence based on an already existing sequence: result = []for item in item_list: new_item = Do_something_with (item) Result.append (item) If you like MapReduce, you can use the map, or the

A, i=1while i: pass In the above Code, while I: executes a loop when I is the true value. In python, except for none, empty string, empty list, empty dictionary, empty tuples, and False, all others are the true values, true. B, while True: pass The above Code applies to an infinite loop, that is, the condition i
