print(cuisine) 系统输出: 蒸羊羔 蒸鹿尾 烧花鸭 烧雏鸡 烧子鹅 以上我们利用for循环实现了不同的功能。 下面着重介绍一个在for loop中循环使用else语句的例子。else 中的语句会在循环正常执行完的情况下执行。 三、把else语句放进for loop 例5:我们写一个简单的奇数偶数判别代码: 输入: for i in list(range...
The for loop and while loop are two different approaches to executing the loop statements in python. They both serve the same functionality of looping over a python code till a condition is being fulfilled. For loops and while loops differ in their syntax. In while loops, we have to mention...
With Python, you can use `while` loops to run the same task multiple times and `for` loops to loop once over list data. In this module, you'll learn about the two loop types and when to apply each.
4- Use a “while loop” to print the values contained in “mylist”, one at a time. 1i =02whilei <len_mylist:3print('mylist','[',i,']','=',mylist[i])4i += 1 5- Create a numpy array using the values contained in “mylist”. Name it “myarray”. ...

The Python while loop: you'll learn how you can construct and use a while loop in data science applications. You'll do this by going over some interactive coding challenges. Next, you'll move on to the for loop: once again, you'll learn how you can construct and use a for loop in...
