self is inevitable. There was just a question should self be implicit or explicit. Guido van Rossum resolved this question saying self has to stay. So where the self live? If we would just stick to functional programming we would not need self. Once we enter the Python OOP we find self there. Here is the typical use case class C with the method m1

2016年10月18日 · Adding an answer because Oskarbi's isn't explicit. You use self when:. Defining an instance method. It is passed automatically as the first parameter when you call a method on an instance, and it is the instance on which the method was called.

2017年7月8日 · Remember, since self is the instance, this is equivalent to saying jeff.name = name, which is the same as jeff.name = 'Jeff Knupp. Similarly, self.balance = balance is the same as jeff.balance = 1000.0. After these two lines, we consider the Customer object "initialized" and ready for use. Be careful what you __init__

2013年8月27日 · I know _blank opens a new tab when used with the anchor tag and also, there are self-defined targets I use when using framesets but I will like to know the difference between _parent, _self and _top.

@Sqoo - saying "DO NOT USE self::, use static::" is a strange point to make - those are deliberately not the same operation. I think the point you are really making is "it is clearer if you use the actual class name 'MyClass::', rather than 'self::'.

Calling x.create_atm(); in python is the same as calling Bank.create_atm(x);, so now self refers to x. If you add another bank called y, calling y.create_atm() will know to look at y's value of crisis, not x's since in that function self refers to y. self is just a naming convention, but it is very good to stick with it. It's still worth ...

2008年11月27日 · @Bluebird75: Furthermore, I'm not sure I get the argument that threads should not be killed abruptly "because the thread might be holding a critical resource that must be closed properly": this is also true from a main program, and main programs can be killed abruptly by the user (Ctrl-C in Unix, for instance)–in which case they try to handle this possibility as nicely as …

2012年12月17日 · To cut a long story short, the self-signed certificate needs to be installed into npm to avoid SELF_SIGNED_CERT_IN_CHAIN: npm config set cafile "<path to certificate file>" Alternatively, the NODE_EXTRA_CA_CERTS environment variable can be set to the certificate file. I think that's everything I know about getting npm to work behind a proxy ...

2023年4月24日 · If you want to add the self-signed cert, export the cert you want as a Base-64 encoded .CER file. Locate your Git cert.pem file (for me it is in C:\Program Files\Git\usr\ssl\cert.pem). Open up your .CER file in a text-editor, and copy/paste the contents at the end of your cert.pem file. Save the file. Then open up your console and type

2009年2月23日 · super(self.__class__, self).__init__() # DON'T DO THIS! EVER. (That answer is not clever or particularly interesting, but in spite of direct criticism in the comments and over 17 downvotes, the answerer persisted in suggesting it until a kind editor fixed his problem.)
