how to add value to a tuple

Question

I m working on a script where I have a list of tuples like   1   2   3   4    e g    list      1   2   3   4              2   3   4   5              3   4   5   6              4   5   6   7      Now I need to add  1234    2345   3456  and  4567  respectively at the end of each tuple  e g   list      1   2   3   4   1234              2   3   4   5   2345              3   4   5   6   3456              4   5   6   7   4567      Is it possible in any way

As other people have answered  tuples in python are immutable and the only way to  modify  one is to create a new one with the appended elements included   But the best solution is a list   When whatever function or method that requires a tuple needs to be called  create a tuple by using tuple list

As mentioned in other answers  tuples are immutable once created  and a list might serve your purposes better   That said  another option for creating a new tuple with extra items is to use the splat operator   new tuple     old tuple   new    items    I like this syntax because it looks like a new tuple  so it clearly communicates what you re trying to do   Using splat  a potential solution is   list      i     join i   for i in list

Tuples are immutable and not supposed to be changed - that is what the list type is for  You could replace each tuple by originalTuple    newElement    thus creating a new tuple  For example   t    1 2 3  t   t    1   print t  1 2 3 1    But I d rather suggest to go with lists from the beginning  because they are faster for inserting items    And another hint  Do not overwrite the built-in name list in your program  rather call the variable l or some other name  If you overwrite the built-in name  you can t use it anymore in the current scope

In Python  you can t  Tuples are immutable   On the containing list  you could replace tuple   1    2    3    4   with a different   1    2    3    4    1234   tuple though

Based on the syntax  I m guessing this is Python  The point of a tuple is that it is immutable  so you need to replace each element with a new tuple   list    l       join l    for l in list    output     1    2    3    4    1234        2    3    4    5    2345        3    4    5    6    3456        4    5    6    7    4567

I was going through some details related to tuple and list  and what I understood is    Tuples are Heterogeneous collection data type Tuple has Fixed length  per tuple type  Tuple are Always finite   So for appending new item to a tuple  need to cast it to list  and do append   operation on it  then again cast it back to tuple      But personally what I felt about the Question is  if Tuples are supposed to be finite  fixed length items and if we are using those data types in our application logics then there should not be a scenario to appending new items OR updating an item value in it    So instead of list of tuples it should be list of list itself  Am I right on this
