Remove nested records from tuple in Python
When it is required to remove nested record/tuples from a tuple of tuple, a simple loop and the 'isinstance' method and the enumerate method can be used.
The enumerate method adds a counter to the given iterable, and returns it. The 'isinstance' method checks to see if a given parameter belong to a specific data type or not.
Below is a demonstration of the same −
Example
tuple_1 = (11, 23, (41, 25, 22), 19)
print("The tuple is : ")
print(tuple_1)
my_result = tuple()
for count, elem in enumerate(tuple_1):
if not isinstance(elem, tuple):
my_result = my_result + (elem, )
print("Elements after removing the nested tuple is : ")
print(my_result)Output
The tuple is : (11, 23, (41, 25, 22), 19) Elements after removing the nested tuple is : (11, 23, 19)
Explanation
- A tuple is defined, and is displayed on the console.
- Another empty tuple is defined.
- The first tuple is enumerated, and iterated over.
- If the element inside the tuple isn't an instance of a specific type, that element is added to the empty list.
- This operation is assigned to a variable.
- It is displayed as the output on the console.
