[issue39641] concatenation of Tuples

[Ammar Askar]

Ammar Askar <ammar at ammaraskar.com> added the comment:

Are you trying to concatenate a single string? If so keep in mind you need a trailing comma:

>>> (1, 2) + (3, 4) + ('a',)
(1, 2, 3, 4, 'a')
>>> (1, 2) + (3, 4) + ('a')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: can only concatenate tuple (not "str") to tuple
