Assuming that the list obtained from the SQL query is a list of dictionaries, the optimal method to transform it into a dual tuple using Python would be as follows:

# Sample list obtained from SQL query
sql_list = [{'name': 'John', 'age': 25}, {'name': 'Emily', 'age': 30}, {'name': 'Mark', 'age': 28}]

# Transforming the list into a dual tuple
dual_tuple = [(d['name'], d['age']) for d in sql_list]

# Output
print(dual_tuple)
# Output: [('John', 25), ('Emily', 30), ('Mark', 28)]

Explanation:

  • The list of dictionaries (sql_list) is transformed into a dual tuple by using a list comprehension.
  • Each element of the dual tuple is a tuple that contains the values of the 'name' and 'age' keys of each dictionary in the list.
  • The resulting dual tuple is stored in the dual_tuple variable and can be used further in the code.
