Thanks! I wish a Python code would do it! Is there a solution? ---

Of course. Many. Depends on the details of what you want, which you’re not telling us. ---

My secret wish is to find a simple solution as I’m trying to slice and dice and it’s difficult. That’s it. text1 = text[2:27] text2 = text[29:53] text3 = text[55:79] ---

Well, now you’ve already done the slicing and dicing as well. ---

Do you have more details to share? The “smaller strings”, do they require 7 comma separated values? It can be difficult to provide guidance without the full picture 🙂 A good place to start is having a look at [`str` methods](https://docs.python.org/3/library/stdtypes.html#string-methods). One of the best ways to “slice and dice” a string (without [slicing](https://docs.python.org/3/library/functions.html#slice)) is [`str.split`](https://docs.python.org/3/library/stdtypes.html#str.split). Note also, that a strings have concatenation method called `join`. Python also has a [regular expressions facility](https://docs.python.org/3/library/re.html#module-re). ---

I am happy to share the full code. But the point is that this list is constantly changing when the code is running. Therefore, there is always a difference in the slices, because it is not known where the one- and two-digit numbers are. However, this would be important for PDF saving! ![példa1](https://us1.discourse-cdn.com/flex002/uploads/python1/original/3X/e/9/e97504cc468f6e4a208ecce4d4cbe0f57616cd4d.png) ---

I posted a code snippet. I formulated the point above that the text string is constantly changing. Therefore, the slicing may be inaccurate. ---

Strip the leading and trailing commas and spaces with `.strip` and then split it on commas with `.split`. You now have a list of strings. Slice the list into groups of 7 and join each group with `.join` and a comma. ---

> [@MRAB](#): > > Slice the list into groups of 7 How do you know they want that? Maybe they want 3 groups. Seems more likely, even, as they want them in separate variables, and it would be bad to have a dynamic number of variables. ---

… Unless both things are equal because they always have exactly 21 numbers. So many details they’re keeping secret… ---

Thanks! No secret. There is a Hungarian lottery statistics website: [Lottó 567 - Lottó statisztikák](https://www.lotto567.hu/skadinvan_lotto/gyakorisag) From here I buy 4 lists of 7 numbers each. I edit these lists into a connected list. I get a list of 4x7=28 numbers. This is what I process with my program: Save to a json file, then scan and display in tkinter Text. Extraction from Text, I mix the 28 numbers. I reduce the number repetitions to one piece, so usually 23 pieces remain. I will divide this into the numbers of the Scandinavian lottery tickets, which can be made into seven pieces, three tickets in total. Some numbers are missing. I display these three series of numbers again in tkinter Text, then read them from here and save them to PDF. So a problem arises when slicing. I found the solution at night: instead of 1, 2, 3, 4, etc., 01, 02, 03, etc. I have to apply. After a little investigation, I found the solution with the help of print(help(str.zfill)) and data = (f"{1:02}"). You are a great team! ![Képernyőkép 2024-07-15 123706](https://us1.discourse-cdn.com/flex002/uploads/python1/original/3X/9/c/9cc353e85b142c149237dcc25ba9c884daa9bafd.png)
