Following code is trying to create a tuple with a single item.

Q. Following code is trying to create a tuple with a single item. But when we try to obtain the length of the tuple is, Python gives error. Why? What is the solution ?

>>> t = (6)
>>> len(t)
Traceback (most recent call last):
  File "<pyshell#2>", line 1, in <module>
    len(t)
TypeError: object of type 'int' has no len()
>>>

Answer :-

The syntax for a tuple with a single item requires the item to be followed by a comma as

shown below:

t = (6,)

Thus, above code is not creating a tuple in t but an integer, on which len() cannot be applied. To create a tuple in t with single element, the code should be modified as:

>>> t = (6,)
>>> len(t)
