What's the difference between (1,) and (1) in Python [duplicate]

Question

As stated in the title, I found that (1) and (1,) are different. But what's the difference of them?

In[39]: (1) == (1,)
Out[39]: False

Try this to convince yourself:

>>> type((1))
<type 'int'>
>>> type((1,))
<type 'tuple'>

The following identity checks may provide you with further insight into the differences:

>>> (1) is 1
True
>>> (1,) is 1
False

The comma makes it a tuple. (1) is just the same as 1 wrapped in delimiters.
