How to create one-element tuple? : Pythoneo

Let’s see how to create one-element tuple in Python.

As you may know one-element tuple is not recognised as a tuple. Paranthesis is not making the element a tuple. For Python such element is a string.

my_tuple = ('Pythoneo')
print(my_tuple)
print(type(my_tuple))

Tuple comma trick

There is a trick to force Python to recognise one-element tuple as a tuple. It is enough to put a comma after such element.

my_tuple = ('Pythoneo',)
print(my_tuple)
print(type(my_tuple))

It may looks strange but actually it is working fine.

Tuple method

Another way to force Python to recognise one-element tuple as a actual tuple is to use a tuple method.

my_tuple = tuple(['Pythoneo'])
print(my_tuple)
print(type(my_tuple))

Please don’t forget using brackets! Without the brackets Python will create a tuple from separate letters.

my_tuple = tuple('Pythoneo')
print(my_tuple)
print(type(my_tuple))

Remark: For sure you noticed that for these tricks Python worked the same. No matter if you put comma at the end of one-element tuple or use tuple methon Python will put comma at the end of output tuple.
