Strings that are not composed of ASCII letters, digits or underscores, are not interned. This explains why 'wtf!' was not interned due to !. CPython implementation of this rule can be found hereWhen a and b are set to "wtf!" in the same line, the Python interpreter creates a new ob...

What does "object destructuring" mean and what is the result of a destructuring operation?Say you have an object with some properties:const person = { firstName: 'Tom', lastName: 'Cruise', actor: true, age: 57 }You can extract just some of the object properties and put them into ...
processing the next line as part of the current one (that is, treat multiple physical lines as a single, logical line). But having to type underscores repeatedly has always been annoying, and in fact, for years the No. 1 feature request has been for the compiler to “just figure it ...

Because name mangling excludes the names ending with double underscores. The third snippet was also a consequence of name mangling. The name __variable in the statement return __variable was mangled to _A__variable, which also happens to be the name of the variable we declared in the outer...
