yield break in Python

Question

According to answer to this question, yield break in C# is equivalent to return in Python. In the normal case, return indeed stops a gener

Answer 1

The funny part is that both functions have the same bytecode. Probably there's a flag that sets to generator when bytecode compiler finds the yield keyword.

>>> def f():
...   return

>>> def g():
...   if False: yield 
#in Python2 you can use 0 instead of False to achieve the same result


>>> from dis import dis
>>> dis(f)
2           0 LOAD_CONST               0 (None) 
            3 RETURN_VALUE
>>> dis(g)
2           0 LOAD_CONST               0 (None) 
            3 RETURN_VALUE
