If-else in for loop In this section, we will see how to use if-else statements with a loop. If-else is used when conditional iteration is needed. For example, print student names who got more than 80 percent. The if-else statement checks the condition and if the condition is True it...
Iterating over the items of an iterable in reverse or sorted order is also a common requirement in programming. To achieve this, you can combine a for loop with the built-in reversed() or sorted() function, respectively.Note: To learn more about reversed() and sorted(), check out the ...

While loops exist in virtually all programming languages, the Pythonforloop function is one of the easiest built-in functions to master since it reads almost like plain English.In this tutorial, we’ll cover every facet of theforloop. We’ll show you how to use it with a range of example...

Python provides two keywords to terminate a loop prematurely, they are Break and Continue. Break statement terminates the loopimmediately, we can introduce the break keyword with aconditional statementlikeifin our program. list= [1,2,3,4,]foriinlist:ifi ==3:breakprint(i) ...
For example, say that you want to implement a number-guessing game. You can do this with awhileloop: Pythonguess.py fromrandomimportrandintLOW,HIGH=1,10secret_number=randint(LOW,HIGH)clue=""# Game loopwhileTrue:guess=input(f"Guess a number between{LOW}and{HIGH}{clue}")number=int(guess...

Python 里面的「for 循环」很像读英文。通用形式的 for loop 如下: for a in A do something with a 1. 2. 其中for 和 in 是关键词,A 是个可迭代数据 (list, tuple, dic, set),a 是 A 里面的每个元素 enumerate 函数 enumerate(A) 不仅可以 A 中的元素,还顺便给该元素一个索引值 (默认从 0 开...
