迭代(编程): 按顺序访问一个列表中的每一项, 在很多编程语言中表现为foreach语句: $arr= [1,2,3,4];foreach($arras$i)echo$i; 遍历: 按一定规则访问一个非线性的结构中的每一项, 强调非线性结构(树, 图). 而迭代一般适用于线性结构(数组, 队列). 结论 循环(loop) - 最基础的概念, 所有重复的行为 递归(recur

This is the primary way to iterate through a dictionary in Python. You just need to put the dictionary directly into a for loop, and you’re done!If you use this approach along with the [key] operator, then you can access the values of your dictionary while you loop through the keys:...
To iterate through a list in Python, the most straightforward method is using aforloop. The syntax is simple:for item in list_name:, whereitemrepresents each element in the list, andlist_nameis the list you’re iterating over. For example, if you have a list of city names likecities ...

Example 1: Using zip (Python 3+) list_1 = [1, 2, 3, 4] list_2 = ['a', 'b', 'c'] for i, j in zip(list_1, list_2): print(i, j) Run Code Output 1 a 2 b 3 c Using zip() method, you can iterate through two lists parallel as shown above. The loop runs until...
You need to iterate this for any number of layers and promote the user to enter the number of layers and the function will draw all the hexagons in one go. 大意是你需要用python画一个正六边形,然后用其他正六边形包围它,之后你就会有7个正六边形。运行时需要用户要给出六边形的层数,程序会画出...
