In Python, we can loop over list elements with for and while statements, and list comprehensions. Python list loop with for Python for statement iterates over the elements of a list in the order that they appear in the list. list_loop_for.py #!/usr/bin/python words = ["cup", "star...
>>> 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...
Print all items in the list, one by one: thislist = ["apple", "banana", "cherry"] for x in thislist: print(x) Try it Yourself » Learn more about for loops in our Python For Loops Chapter.Loop Through the Index NumbersYou...
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...
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....
在python中,有两种方法可以实现迭代流程: Using theforloop 使用for循环 Using thewhileloop 使用while循环 for循环 (Theforloop) Let us first see what's the syntax, 首先让我们看看语法是什么 for [ELEMENT] in [ITERATIVE-LIST]: [statement to execute] ...
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:...
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) ...

Python for loops with range Pythonrangefunction generates a list of numbers. range(n) The function generates numbers 0...n-1. range(start, stop, [step]) The function generates a sequence of numbers; it begins withstartand ends withstop, which is not included in the sequence. Thestepis ...
