In this section, we will see how to useif-else statementswith 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 c
In Python, for loops are compound statements with a header and a code block that runs a predefined number of times. The basic syntax of a for loop is shown below:Python Syntax for variable in iterable: In this syntax, variable is the loop variable. In each iteration, this variable...

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) ...

We can also utilize the attributes of the objects (find through “dir” and “help”) for the iteration purpose. Similar to “while” we can also use “break” and “continue” statements in “for” loop as well. Now we are done with the conditional statements and move forward with othe...
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...

有了列表表达式，你就不再需要用 for loop 来生成一个 list 了。其基本语法是这样的： [ expression for item in list if conditional ] 这就是一个生成包含一串数字的 list 的简单例子。 在这条命令里还可以使用表达式（expression），所以也可以做一些数学运算： 你甚至可以调用一个外部函数： 最后，你也可以...
