Put it simple decorator allow you to modify a given function's definition without touch its innermost (it's closure).Sat, 11 Apr 2026 11:47:00 GMThttps://stackoverflow.com/questions/26000198/what-does-colon-equal-in-python-meanIn Python this is simply =. To translate this pseudocode into Python you would need to know the data structures being referenced, and a bit more of the algorithm implementation. Some notes about psuedocode: := is the assignment operator or = in Python = is the equality operator or == in Python There are certain styles, and your mileage may vary:Sat, 11 Apr 2026 12:59:00 GMThttps://stackoverflow.com/questions/22832615/what-do-and-mean-in-pythonI notice that I can do things like 2 << 5 to get 64 and 1000 >> 2 to get 250. Also I can use >> in print: print >>obj, "Hello world" What is happening here?Thu, 09 Apr 2026 21:37:00 GMThttps://stackoverflow.com/questions/36901/what-does-double-star-asterisk-and-star-asterisk-do-for-parametersSee What do ** (double star/asterisk) and * (star/asterisk) mean in a function call? for the complementary question about arguments.Thu, 26 Mar 2026 13:46:00 GMThttps://stackoverflow.com/questions/509211/how-slicing-in-python-worksPython slicing is a computationally fast way to methodically access parts of your data. In my opinion, to be even an intermediate Python programmer, it's one aspect of the language that it is necessary to be familiar with.Thu, 26 Mar 2026 19:08:00 GMThttps://stackoverflow.com/questions/2209755/python-operation-vs-is-notIn a comment on this question, I saw a statement that recommended using result is not None vs result != None What is the difference? And why might one be recommended over the other?Wed, 08 Apr 2026 21:16:00 GMThttps://stackoverflow.com/questions/2451386/what-does-the-caret-operator-doSide note, seeing as Python defines this as an xor operation and the method name has "xor" in it, I would consider it a poor design choice to make that method do something not related to xor like exponentiation. I think it's a good illustrative example of how it simply calls the __xor__ method, but to do that for real would be bad practice.Sat, 11 Apr 2026 12:16:00 GMThttps://stackoverflow.com/questions/400739/what-does-asterisk-mean-in-pythonWhat does asterisk * mean in Python?

The implementation will allocate more space automatically, according to what is necessary to represent the number. (For example, if the value would "fit" in one machine word, then only one is used; the data type abstracts the process of sign-extending the number out to infinity.)Sun, 12 Apr 2026 05:05:00 GMThttps://stackoverflow.com/questions/3294889/iterating-over-a-dictionary-using-a-for-loop-getting-keysWhy is it 'better' to use my_dict.keys() over iterating directly over the dictionary? Iteration over a dictionary is clearly documented as yielding keys. It appears you had Python 2 in mind when you answered this, because in Python 3 for key in my_dict.keys() will still have the same problem with changing the dictionary size during iteration.Sat, 11 Apr 2026 20:08:00 GMT
