Question

我正在打开这个帖子，因为我想知道如何以及是否可以自定义列表输出：

1       2.33     KG
2       3.0      KG
3       (empty)   3
x       222      KG
y       233.4    KG
y       112      %
z       222      KG
w       9.98     KG
a       3224     KG
...     ....    ....

有人可以告诉我吗？

Answer 1

根据您尝试的操作，您可以试用pandas，它非常适合处理和打印2d数组，或string formatting中讨论的this answer

Answer 2

尝试在列表中构建列表。像[[1,2,33，KG]，[2,3.0，KG]，[3，＆＃39; ＆＃39;，3]] 然后，您可以通过迭代列表来访问每个元素。

<table>    
for i in [[1 ,2.33 ,KG],[2, 3.0,KG],[3,' ',3]]:
    <tr>
    for j in i:
       <td>j</td> 
    </tr>
 </table>

Answer 3

Please show your code. But I assume you want to know how to do what you've typed above.

Preferably, you'd want to place the variables in a list of tuples like this:

your_tuple_list_name = [(1, 2.33, 'KG'), (2, 3.0, 'KG'), (3, '(empty)', 'KG'), ('x', 222, 'KG'), ('y', 233.4, 'KG'), ('y', 112, '%'), ('z', 222, 'KG'), ('w', 9.98, 'KG'), ('a', 3224, 'KG'), ('.', '....', '..'), (add other tuples here)]`

If you want to add more items to the list of tuples just add them following the format:

(first_column, second_column, third_column)

And then the method would be like this:

def formatted_printing(your_tuple_list):
    space = ' '
    for n in range(len(your_tuple_list)):
        number = 8 - len(str((your_tuple_list[n][1])))
        print("{:>}    {:<}{}{:<}".format(your_tuple_list[n][0], your_tuple_list[n][1], (space * number), your_tuple_list[n][2]))


formatted_printing(your_tuple_list_name)

With the following being the output:

1    2.33    KG
2    3.0     KG
3    (empty) KG
x    222     KG
y    233.4   KG
y    112     %
z    222     KG
w    9.98    KG
a    3224    KG
.    ....    ....
