Soothsayer added the comment: Correction: it's a dictionary comprehension, and it did indeed used to be a call to dict() in the 2.7 documentation. ---------- versions: +Python 3.7 _______________________________________ Python tracker https://bugs.python.org/issue32722 _______________________________________

Stéphane Wirtel added the comment: This example is also in 2.7 https://docs.python.org/2.7/tutorial/classes.html#generator-expressions -> I add 2.7 ---------- nosy: +matrixise versions: +Python 2.7 _______________________________________ Python tracker https://bugs.python.org/issue32722 _______________________________________

Soothsayer added the comment: I agree that 2.7 is incorrect also, 2.7 has dict comprehensions also so there's no reason to pass a generator expression to dict(). I add 3.4 and 3.8 because they also have the problem. ---------- versions: +Python 3.4, Python 3.8 _______________________________________ Python tracker https://bugs.python.org/issue32722 _______________________________________

Xiang Zhang added the comment: I treat it as an enhancement so only merge it into 3.8. Thanks Soothsayer for the report and Stéphane for the patch! ---------- resolution: -> fixed stage: patch review -> resolved status: open -> closed versions: -Python 2.7, Python 3.4, Python 3.5, Python 3.6, Python 3.7 _______________________________________ Python tracker https://bugs.python.org/issue32722 _______________________________________
