I am having some trouble with aligning things in my output. Down below I have copied the expected output and the output my code gives me. It is very similar, however, the numbers aren't aligned correctly. My numbers would align to the right (and this first column can only be as long as the longest number in this column). What am I forgetting in my code?

I am trying to get the output of my code formatted in the following way:

So I have a list of strings:

I'm scraping a website that has a table of satellite values (https://planet4589.org/space/gcat/data/cat/satcat.html).

Because every entry is only separated by whitespace, I need a way to split the string of data entries into an array.

However, the .split() function does not suit my needs, because some of the data entries have spaces (e.g. Able 3), I can't just split everything separated by whitespace.

It get's trickier, however. In some cases where no data is available, a dash ("-") is used. If two data entries are separated by only a space, and one of them is a dash, I don't want to include it as one entry.

e.g say we have the two entries "Able 3" and "-", separated only by a single space. In the file, they would appear as "Able 3 -". I want to split this string into the separate data entries, "Able 3" and "-" (as a list, this would be ["Able 3", "-"]).

Another example would be the need to split "data1 -" into ["data1", "-"]

Pretty much, I need to take a string and split it into a list or words separated by whitespace, except when there is a single space between words, and one of them is not a dash.

Also, as you can see the table is massive. I thought about looping through every character, but that would be too slow, and I need to run this thousands of times.

Here is a sample from the beginning of the file:

My question is: how I can define an input code that the user can be entered for example 3, 5, 6, or any number to get an output with 3 letters, 5 letters and etc(according to user input).

Output for this code is:

My function doesn't take any arguments but I get this error not enough values to unpack (expected 2, got 0). I can print the values on the terminal but can't be displayed on the browser.

I am fetching data from two database tables(Postgres) and put it in a select input in Django template.

This is the method suppose to return the data to be displayed
