>>> numbers = [1,2,3,4,5,6,7,8,9] 您还可以使用 Python 内置方法向列表中添加元素。例如,append方法可用于向列表中插入元素。元素被添加到列表的最后位置,如下所示: >>> numbers.append(10) >>>print(numbers) [1,2,3,4,5,6,7,8,9,10] 我们还可以创建一个包含多种类型值的列表,如下例所示...
Consider the following example that compares swapping with a temporary variable and unpacking: Python >>> a = "foo" >>> b = "bar" >>> # Using a temporary variable >>> temp = a >>> a = b >>> b = temp >>> a, b ('bar', 'foo') >>> a = "foo" >>> b = "bar" ...

Way 3: Bubble sort in Python with user input We can modify the Python program to takeuser inputfor the list that needs to be Bubble sorted. Here’s an example of how to do it: Code: # Taking user input for the list of numbers ...
Here, we can see that the code is very less and more readable. If instead, we were to use Java, the same program would have to be written in the following way: publicclassSwap{publicstaticvoidmain(String[] args){inta,b,temp;a= 15;b= 27;System.out.println("Before swapping : a, ...
Unpacking Tuples With Enumerate:Make use of the enumerate function to easily unpack tuples and access the index and value of elements in an iterable. This will result in clear and concise code when iterating over sequences. Simultaneous Variable Swapping:Using Python’s elegant syntax, you can...
For example, you can use this operator to collect multiple values in a single variable when the number of variables on the left doesn’t match the number of items in the tuple on the right:Python >>> numbers = (1, 2, 3, 4, 5) >>> *head, last = numbers >>> head [1, 2,...
