for i in list1: for j in list2: print((i, j)) 在这个例子中,外层循环遍历第一个列表,内层循环遍历第二个列表,从而生成所有可能的组合。 3. 实现复杂的条件判断 嵌套循环还可以用于实现复杂的条件判断。例如,查找两个数组中满足特定条件的元素对。 list1 = [1, 2, 3] list2 = [4, 5, 6] for...
menu=['蒸羊羔','蒸鹿尾','烧花鸭','烧雏鸡','烧子鹅'] for cuisine in menu: print(cuisine) 系统输出: 蒸羊羔 蒸鹿尾 烧花鸭 烧雏鸡 烧子鹅 以上我们利用for循环实现了不同的功能。 下面着重介绍一个在for loop中循环使用else语句的例子。else 中的语句会在循环正常执行完的情况下执行。 三、把else...
What is for loop in Python In Python, theforloop is used to iterate over a sequence such as alist, string,tuple, other iterable objects such asrange. With the help offorloop, we can iterate over each item present in the sequence and executes the same set of operations for each item. ...
一种是for...in...循环语句,另一种是while循环语句。 一、for循环: for循环格式: 代码示例 代码语言:javascript 代码运行次数:0 运行 AI代码解释 foriin[1,2,3,4,5]:print(i) 运行效果图: 当然这里循环的不仅仅可以是列表,也可以是字典和字符串,不可以是整数、浮点数, 如果是字典的话,循环打印出来的是...
In Python, we use a for loop to iterate over various sequences, such as lists, tuples, sets, strings, or dictionaries. The for loop allows you to iterate through each element of a sequence and perform certain operations on it. In this tutorial, we will e
Python loop循环实例: >>>languages = ["C","C++","Perl","Python"]>>>forxinlanguages: ...print(x) ... C C++Perl Python>>> 以下for 实例中使用了 break 语句,break 语句用于跳出当前循环体: #!/usr/bin/python3sites = ["Baidu","Google","Runoob","Taobao"]forsiteinsites:ifsite =="Run...
在Python中,for循环用以下的格式构造: for[循环计数器]in[循环序列]:[执行循环任务] Copy [循环任务]在循环序列用尽之前,将会将一直被执行。 我们来看看这个例子中,如何用for循环去重复打印一个区间内的所有数字: foriinrange(0,5):print(i) Copy
One Line for Loop in Python The simplified “for loop” in Python is one line for loop, which iterates every value of an array or list. The one line for the loop is iterated over the “range()” function or other objects like an array, set, tuple, or dictionary. ...
Python中的for循环,没你想的那么简单~ 一年四季,循环往复:说到底就是一个循环的问题 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语句其实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:...
However, to learn more about them, check out the Iterators and Iterables in Python: Run Efficient Iterations tutorial. You can also have a loop with multiple loop variables: Python >>> points = [(1, 4), (3, 6), (7, 3)] >>> for x, y in points: ... print(f"{x = } ...
