== operator compares the values of both the operands and checks if they are the same. So is is for reference equality and == is for value equality. An example to clear things up, >>> class A: pass >>> A() is A() # These are two empty objects at two different memory locations...

It allows them to be used as dictionary keys and set elements Makes them hashable, safe to share, and more memory efficient They are often used to return multiple values safely ✅ Summary QuestionAnswer Can a tuple be modified? ❌ No, tuples are immutable Why does += seem to change ...
Each LuaRuntime is protected by a global lock that prevents concurrent access to it. The low memory footprint of Lua makes it reasonable to use multiple runtimes, but this setup also means that values cannot easily be exchanged between threads inside of Lua. They must either get copied ...
if、elif和else if是最广为人知的控制流语句。它检查一个条件,如果为True,就执行后面的语句: if x < 0: print('It's negative') if后面可以跟一个或多个elif,所有条件都是False时,还可以添加一个else: if x < 0: print('It's negative') elif x == 0: print('Equal to zero') elif 0 < ...
