wish of those help Seems like you have assigned some tuple value to variable range. Use del range to reset it, then range(0, 2) will evaluate properly.

Mutate tuple of lists getting "'tuple' object does not support item assignment“

Any of those help += is the in-place addition operator. It does two things:
it calls obj.__iadd__(rhs) to give the object the opportunity to mutate the object in-place. it rebinds the reference to whatever the obj.__iadd__(rhs) call returns.
code :
>>> reference = somestr = 'Hello'
>>> somestr += ' world!'
>>> somestr
'Hello world!'
>>> reference
>>> reference is somestr
>>> reference = somelst = ['foo']
>>> somelst += ['bar']
>>> somelst
['foo', 'bar']
>>> reference
['foo', 'bar']
>>> reference is somestr
>>> t = ([1,2],)
>>> t[0].extend([3, 4, 5])
>>> t[0]
[1, 2, 3, 4, 5]

Returing tuple giving an error tuple object is not callable

To fix this issue You should not be calling properties. Instead, you access them like normal attributes:
code :
def execute(self):
    print self.get_features
class Foo(object):

hope this fix your issue I have this function in python: , You have a trailing comma on this line:

initializing std::tuple which element constructors require object from another std::tuple

hope this fix your issue
How should I initialize m_Cs if I need to initialize std::get(m_Cs) with std::get(m_Bs) i.e. constructor of each element in m_Cs requires a corresponding element from m_Bs
code :
  template <std::size_t ... Is>
  A (std::index_sequence<Is...> const &, As const & ... args)
     : m_Bs{B<As>{args}...}, m_Cs{std::get<Is>(m_Bs)...}
   { }

  A (As const & ... args)
     : A{std::index_sequence_for<As...>{}, args...}
   { }
#include <tuple>
#include <type_traits>

template <typename T>
struct B
 { B (T const &) {} };

template <typename T>
struct C
 { C (T const &) {} };

template <typename ... As>
struct A
      using Bs = std::tuple<B<As>...>;
      using Cs = std::tuple<C<B<As>>...>;

      Bs m_Bs; 
      Cs m_Cs;

      template <std::size_t ... Is>
      A (std::index_sequence<Is...> const &, As const & ... args)
         : m_Bs{B<As>{args}...}, m_Cs{std::get<Is>(m_Bs)...}
       { }

      A (As const & ... args)
         : A{std::index_sequence_for<As...>{}, args...}
       { }

int main()
   A<int, long, long long> a{1, 2L, 3LL};

TypeError: 'tuple' object does not support item assignment On non tuple object

like below fixes the issue this code takes an ordered (highest score to lowest score) list of tuples and gathers the name and score of the highest, second highest and third highest scorers. If theirs a tie, both names are appended to the same list. , Here is my solution:
code :
from collections import defaultdict
given_list = [('Raven', '18'), ('Cobra', '8'), ('Lion', '6'), ('Python', '6'),('Otter', '2')]
reversed_dict = defaultdict(list)
for key,value in given_list:

for k in reversed(sorted(reversed_dict)[-3:]):
18 ['Raven']
8 ['Cobra']
6 ['Lion', 'Python']
