Hi all: I notice that if concatenating two stringobjects, PVM will not check the dictionary of interned string. For example:
>>> a = "qwerty" >>> b = "qwe" >>> c = "rty" >>> d = b+c >>> id(a) 4572089736 >>> id(d) 4572111176 >>> e = "".join(["qwe","rty"]) >>> id(e) 4546460280 But if concatenating two string directly, PVM would check the dictionary: >>> a = "qwerty" >>> b = "qwe"+"rty" >>> id(a) 4546460112 >>> id(b) 4546460112 It happens in Py2 and Py3 both. Is it necessary for fixing this bug or not? Cheers! --- Yinbin
