Python has no value called
null, so your question doesn’t make sense.x == nullwill raise a NameError.Answer to your updated question: Yes, it will enter the if statement.
Noneis false in a boolean context, sonot Noneis true. You can see this yourself in the interactive interpreter:If you’re coming from a Java background, you should realize that Python makes it much easier to try things out. Get used to trying things in the Python interpreter. A lot of questions can easily be answered just by trying things yourself and seeing what happens.
