在很多的高级语言中都有for循环(for loop)。for语句是编程语言中针对可迭代对象的语句,它的主要作用是允许代码被重复执行。看一段来自维基百科的介绍: Incomputer science, afor-loop(or simplyfor loop) is acontrol flowstatementfor specifyingiteration, which allows code to beexecutedrepeatedly。(作用:介绍了f...
In computer science, afor-loop(or simplyfor loop) is a control flow statement for specifyingiteration, which allows code to be executed repeatedly。(作用:介绍了for循环是什么?) A for-loop has two parts: a header specifying the iteration, and a body which is executed onceper iteration. (for...

>>>for i in range(1,11): >>> print(i) for 首先for就是代表for陳述句,這個陳述的尾端一定要加上冒號:,Python才會知道有重複性質的工作要做囉,而且要做的事情必須縮排呈現,才是for的工作範圍。 for陳述句的功能是要幫你執行性質類似的重複工作,印出1到10的每個整數,就是從1開始,後一個數字是前一個...
for i in range(3): if i == 2: break print(i, end=' ') # 打印0和1 else: print("Loop completed without encountering a 'break' statement.")5.循环控制语句：range()函数：生成一个起始默认为0的序列，通常与for循环一起使用。def print_numbers(n): for i in range(1, n+1): print(i)...
for iterator in sequence: block of statements else: block of statements Example 1 - Using range function to loop n times The example here iterates over the range of numbers from 1 to 10 and prints its value. However, if it reaches the number divisible by 5, it will break the loop. No...
for i in range(1, 11): # nested loop # to iterate from 1 to 10 for j in range(1, 11): # print multiplication print(i * j, end=' ') print() 1. 2. 3. 4. 5. 6. 7. 8. 输出: 在这个程序中,外部 for 循环是从 1 到 10 迭代数字。 range() 返回 10 个数字。 所以外循环...

循环,但它的设计目的是对一系列操作执行特定次数。Python for 循环可以通过使用内置的range和xrange 方法来模拟该行为。清单 6 中演示了这两种方法。 清单6. range 和 xrange 方法 >>> r = range(10) >>> print r [0, 1, 2, 3, 4, 5, 6, 7, 8, 9] ...
