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數字加1(就是間隔1),這樣的重複性工作。 變數i i是...
Incomputer science, afor-loop(or simplyfor loop) is acontrol flowstatementfor specifyingiteration, which allows code to beexecutedrepeatedly。(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 once per...

Syntax of for loop for i in range/sequencee: statement 1 statement 2 statement n In the syntax, i is the iterating variable, and the range specifies how many times the loop should run. For example, if a list contains 10 numbers then for loop will execute 10 times to print each number...
for looper in range(1, 10): print(9,"*",looper, "=", 9 * looper) 1. 2. 2、range()函数的通常用法: 通常记数方式,从0开始,我们计算机进行运算时,通常以0为起点。 for i in range(0, 5): print("hello") 1. 2. 3、range()简写 ...
Python range is one of thebuilt-in functions. When you want the for loop to run for a specific number of times, or you need to specify a range of objects to print out, the range function works really well. When working withrange(), you can pass between 1 and 3 integer arguments to...
for语句实际上解决的是循环问题。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 be...
