>>> 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...
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...
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....
Using the for loop to iterate over a Python list or tuple ListsandTuplesare iterable objects. Let’s look at how we can loop over the elements within these objects now. words=["Apple","Banana","Car","Dolphin"]forwordinwords:print(word) ...
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....
为什么loop-in函数不在python中循环 function loops for-loop 在python I中,我试图创建一个逗号函数,该函数接受一个参数列表并添加add,并且在所有元素的末尾加上空格,在最后一个元素之前添加“and”在最后一个元素之后没有逗号def comma(listhere): if len(listhere) > 0: for x in listhere: listhere....

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) ...
