Check order specific data type in tuple in Python
When it is required to check the order of a specific data type in a tuple, the 'isinstance' method and the 'chained if' can be used.
The 'isinstance' method checks to see if a given parameter belong to a specific data type or not.
The 'chained if' is a chained conditional statement. It is a different way of writing nested selection statements. It basically means multiple if statements are combined using 'and' operator, and their result is evaluated.
A list can be used to store heterogeneous values (i.e data of any data type like integer, floating point, strings, and so on).
Below is a demonstration of the same −
Example
my_tuple = ('Hi', ['there', 'Will'], 67) print("The tuple is : ") print(my_tuple) my_result = isinstance(my_tuple, tuple) and isinstance(my_tuple[0], str) and isinstance(my_tuple[1], list) and isinstance(my_tuple[2], int) print("Do all instances match the required data type in the same order ? ") print(my_result)
Output
The tuple is : ('Hi', ['there', 'Will'], 67) Do all instances match the required data type in the same order ? True
Explanation
- A tuple of list is defined, and is displayed on the console.
- the 'isinstance' method is used to check if the elements ina tuple belong to a certain data type.
- This is done for all elements within the tuple list, hence the 'and' operator is used to chain the operation.
- This is assigned to a value.
- It is displayed on the console.
