>>> aList.append(bList) >>> aList [3, 4, 5, ['a', 'b', 'c']] #bList列表作为一个元素添加进了aList >>> aList.extend(bList) >>> aList [3, 4, 5, ['a', 'b', 'c'], 'a', 'b', 'c'] #bList各元素添加进了aList 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 1...
Python list loop shows how to iterate over lists in Python. Python loop definition Aloopis a sequence of instructions that is continually repeated until a certain condition is reached. For instance, we have a collection of items and we create a loop to go through all elements of the collecti...
方法二:使用列表推导式 此外,Python 提供了一个非常强大的功能——列表推导式,它能够让我们更加简洁地生成列表。与上面的代码相比,它更为优雅: # 原始整数列表numbers=[1,2,3,4,5]# 使用列表推导式计算平方squares=[num**2fornuminnumbers]print(squares)# 输出: [1, 4, 9, 16, 25] 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 print(sum) ...
The for loop in Python is an iterating function. If you have a sequence object like alist, you can use the for loop to iterate over the items contained within the list. The functionality of the for loop isn’t very different from what you see in multiple other programming languages. ...
In this tutorial, you’ll learn how to loop through a list of integers in Python and perform operations on each element within the list. We’ll explore different examples to demonstrate this concept.The table of contents is structured as follows:...
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. Using aforloops in Python we...
In Python, the for loop is particularly versatile and user-friendly. It directly iterates over items of any sequence (such as a list or string), in the order that they appear, without requiring the indexing used in some other languages. This feature simplifies the process of looping through...
