How to check if a variable is tuple in Python
In this tutorial, we are going to learn about how to check if a variable is tuple or not in Python with the help of examples.
Consider, that we have the following variable in our code:
nums = (4, 5, 6)
Now, we need to check whether the above variable is a tuple or not.
Using type() function
To check if a variable is a tuple or not, we can use the built-in
type() function in Python.
type() function takes the variable as an argument and returns the type of the following object.
Here is an example:
nums = (4, 5, 6) if type(nums) == tuple: print('Variable is tuple') else: print('Variable is not a tuple')
'Variable is tuple'
In the above code,
We have first initialized the variable with a tuple.
Then we used the
==operator to check if both values refer to the same object.
If it returns
True then it prints the
variable is tuple, if the variable is not a tuple then it returns
False and prints
Variable is not a tuple.
nums = [4, 5, 6] if type(nums) == tuple: print('Variable is tuple') else: print('Variable is not a tuple')
'Variable is not a tuple'
Using isinstance() function
Similarly, we can also use the
isinstance() function in Python to check if a given variable is tuple.
isinstance() function takes the two arguments, the first argument is
object, and the second argument is
type then It returns
True if a given object is a specified type otherwise it returns
nums = (4, 5, 6) if isinstance(nums, tuple): print('Variable is tuple') else: print('Variable is not a tuple')
