What determines which strings are interned and when?
python, string-interning
Solution
String interning is implementation specific and shouldn't be relied upon, use equality testing if you want to check two strings are identical.
Problem
``` >>> s1 = "spam" >>> s2 = "spam" >>> s1 is s2 True >>> q = 'asdalksdjfla;ksdjf;laksdjfals;kdfjasl;fjasdf' >>> r = 'asdalksdjfla;ksdjf;laksdjfals;kdfjasl;fjasdf' >>> q is r False ``` How many characters should have to `s1 is s2` give `False`? Where is limit? i.e. I am asking how long a string has to be before python starts making separate copies of it.
