Comment out the |= line and it prints "{'b':2}" as expected.
$ cat t.py
scoped_dict = {'b':2}
def scoped_def():
print(scoped_dict)
scoped_dict |= {'a',1}
scoped_def()
$ p t.py
Traceback (most recent call last):
File "/home/jabowery/dev/t.py", line 5, in <module>
scoped_def()
File "/home/jabowery/dev/t.py", line 3, in scoped_def
print(scoped_dict)
UnboundLocalError: local variable 'scoped_dict' referenced before assignment
$ python --version
Python 3.10.0

This is not a bug. You are getting an UnboundLocalError because in the scope of scoped_def function, scoped_dict is marked as local (because you assign to it in the function) but you are reading it before that. Please, take a look at: https://docs.python.org/3/faq/programming.html#why-am-i-getting-an-unboundlocalerror-when-the-variable-has-a-value and possibly at https://docs.python.org/3.3/tutorial/classes.html#python-scopes-and-namespaces https://docs.python.org/3/library/exceptions.html#UnboundLocalError |
