这是一个创建于 1864 天前的主题，其中的信息可能已经有所发展或是发生改变。
就是把用户输入的 list 里的数字转换成 x 数量的星号。目前卡在两个地方
1.input （）命令可以输入 list 吗？
2. 可以直接用加减乘除来打印出相对应数量的星号吗？
感谢
Problem 2:
Write a function that takes a list of numbers as parameters. Then print a histogram based on those numbers. Use asterisks to draw the histogram.
For example, given the list [3, 7, 9, 5]. The function should produce the following:
***
*******
*********
*****
Call the function with the list [3, 7, 9, 5].
Then call the function with the list [2, 0, 1].
Hint: List was covered in the A3 notebook. We will formally discuss list in A5 notebook.
You might want to first write the histogram code without a function. Then after code is working, write the code with a function. Please submit only the code with a function.

 | 2 qefrgty 2020-10-20 21:00:29 +08:00 via Android 先想办法取 list 的元素， 然后把这个元素赋值给一个变量， 然后打印变量个星号。 emmmm…这是最基本的思路了吧… |

 | 4 lambdafate 2020-10-20 21:04:53 +08:00 1. "Write a function that takes a list of numbers as parameters. ". 不需要 input 吧，list 作为函数参数传进来 2. 可以这样 >>> "*" * n # n 是一个整数 |
 | 5 gypsy OP @learningman @qefrgty @user8341 @lambdafate 做完了，输出是对的，感谢。 import ast list=ast.literal_eval(input()) def star(a): return "*" * a for i in list: print(star(i)) |
