Python customize List output

Question

I am opening this thread because I would like to know how and if it is possible to customize the list output like this:

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
...     ....    ....

Could someone please let me know?

Depending on what you are trying to do you could try out either pandas, which is great at handling and printing 2d arrays, or string formatting discussed in this answer

Try to construct a list inside a list. like [[1 ,2.33 ,KG],[2, 3.0,KG],[3,' ',3]] Then you can access each element by iterating over the lists.

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

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
.    ....    ....

Thank you so much, it really helped me a lot ^_^ – Soichiro Jul 21 '17 at 19:53 — Soichiro, Jul 21 '17 at 19:53
