Loop Through a ListYou can loop through the list items by using a for loop:ExampleGet your own Python Server Print all items in the list, one by one: thislist = ["apple", "banana", "cherry"] for x in thislist: print(x) Try it Yourself » ...
for i in list(range(5)): print(i) 系统输出: 0 1 2 3 4 这是一个最简单的for循环。list(range(5))代表的实体为[0,1,2,3,4]. 上述循环的含义就是生成一个变量i,并让i指代list[0,1,2,3,4]中的每一个数字,并进行输出。 例2: 输入: sum=0 for x in list(range(10)): sum=sum+x ...
In Python, we use a for loop to iterate over sequences such as lists, strings, dictionaries, etc. For example, languages = ['Swift', 'Python', 'Go'] # access elements of the list one by one for lang in languages: print(lang) Run Code Output Swift Python Go In the above example...
# for loop that iterates over the cities list for city in cities: print(city.title()) 1. 2. 3. 4. 5. For循环的组成部分: 循环的第一行以关键字for开始,表示这是一个for循环 然后是iteration_variableiniterable,表示正在被遍历的是可迭代的对象,并且用迭代变量表示当前正在被处理的可迭代对象的元素...
1.for-loop和列表 在开始使用 for 循环之前,你需要在某个位置存放循环的结果。最好的方法是使用列表(list),顾名思义,它就是一个按顺序存放东西的容器。如 何创建列表: hairs = [‘brown’, ‘blond’, ‘red’] eyes = [‘brown’, ‘blue’, ‘green’] ...
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: Incomputer science, afor-loop(or simplyfor loop) is acontrol flowstatementfor specifyingiterati...

Aforloop is used for iterating over a sequence (that is either a list, a tuple, a dictionary, a set, or a string). This is less like theforkeyword in other programming languages, and works more like an iterator method as found in other object-orientated programming languages. ...
使用for循环可以遍历一个列表,从最左到最右: 1 2 3 a=["Listof some sort”] forxina: # Do something for every x 2.You can also use aforloop on a dictionary to loop through itskeyswith the following:可以使用for循环通过key值去遍历一个字典 ...
