需要帮助打印列表 [英] Need help printing list

问题描述

我正在用 Python 处理待办事项列表，目前我一直在打印待办事项列表.

I'm working on a todo list in Python and I am currently stuck on printing the todo list.

我有我的添加代码和查看代码:

I have my add code and view code as such:

if sel == '1': #add task        
     name = input("enter task name: ")
     prio = input("enter priority level (High | Medium | Low): ")
     add(todo, name, prio)
     view(task)
elif sel == '3': #print todo list
     view2(task)
     exit

这些是我使用的函数:

def add(todo, x, y):
    todo[x] = y

def view(x):
    x.append(dict(todo))

def view2(x):
    print(x)

第一次选择打印列表选项时，我可以将项目添加到字典中打印字典.我第二次打印它会给出以下输出

I'm able to add items to a dictionary print the dictionary the first time i select the option to print list. The second time i print it gives the below output

[{'test 1': 'low'}, {'test 1': 'low', 'test 2 ': 'low'}]

我的最终目标是获得如下所示的输出，但我无法通过第一堵墙.有什么建议吗?另外，我是否需要打印嵌套字典才能获得编号列表?

my ultimate goal is to get an output as shown below, but i can't get passed this first wall. Any advice? also, would i need to print a nested dictionary to get a numbered list?

1 - test 1 - low
2 - test 2 - low

提前致谢！

推荐答案

假设 view2(x) 是打印函数，x 是你在问题中提到的字典.

Assuming view2(x) is the function for printing and x is the dictionary which you have mentioned in the question.

你可以这样做

def view2(x):
    for key, val in x.items():
        print("{0} - {1}".format(key, val))
