How to access certain part of a string in python?

Question

I have a string which looks like this:

0,1,488,332,165;1,1,553,712,206;2,1,803,1248,219;3,1,2222,1285,398

The actual string is way more longer than this ...

I need to access the 488, 553, 803 and 2222 but the problem is that these values change.

I don't want to index it because the string is about 1000 characters long.

split by ; split each by , use third - no way aound it. you need toi iterate the string. you could throw away any letter that comes before the second "," - take anything up to the third "," discard anythng up to next ";" then repeat. — Patrick Artner, Feb 08 '22 at 18:16
What do you mean, "these values change"? Their positions? Or the values you're trying to extract? — ddejohn, Feb 08 '22 at 18:19
@ddejohn on the same place, there can be different value every time ... — john78, Feb 08 '22 at 18:22
Are there ALWAYS 5 values between ; - is it always the THIRD value you want? What are the rules? Are there exceptions? — Patrick Artner, Feb 08 '22 at 18:32
Yes there's always 5 values between `;` and I always want the third value after the `;` — john78, Feb 08 '22 at 18:37

you could use list comprehension, and string's split method, to wrap this up in:

result = [x.split(",")[2] for x in string.split(';')]

XxJames07-

`result = [x.split(",")[2] for x in m.split(';')] IndexError: list index out of range` – john78 Feb 08 '22 at 18:27
would be great ! – john78 Feb 08 '22 at 18:35
if there are 5 values and the 3rd value is always there , then it is impossibile that it gives you `IndexError`, maybe you missed a comma, or a semicolen, but this answer only works if the commas in the space between the semicolens are exactly 5. – XxJames07- Feb 08 '22 at 18:49
yeah but in this case there are 4 commas between the semicolen – john78 Feb 08 '22 at 19:09
have solved it finally – john78 Feb 08 '22 at 19:22
