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: Python slicing is a computationally fast way to methodically access parts of your data. This will always return True and "1" == 1 will always return False, since the types differ. So for integers, ~x is equivalent to (-x) - 1. Python is dynamically, but strongly typed, and other statically typed languages would complain about comparing different types. Does * have a special meaning in Python as it does in C? I saw a function like this in the Python Cookbook: def get (self, *a, **kw) Would you please explain it to me or point out where I can find an In 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? May 5, 2011 · As far as the Python languages is concerned, _ generally has no special meaning. There's also the else clause: Python slicing is a computationally fast way to methodically access parts of your data. In 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? Mar 16, 2017 · Why is it 'better' to use my_dict. invert. The only exception are match statements since Python 3. Jun 16, 2012 · There's the != (not equal) operator that returns True when two values differ, though be careful with the types because "1" != 1. . 96 What does the “at” (@) symbol do in Python? @ symbol is a syntactic sugar python provides to utilize decorator, to paraphrase the question, It's exactly about what does decorator do in Python? Put it simple decorator allow you to modify a given function's definition without touch its innermost (it's closure). 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. Python is an interpreted, interactive, object-oriented (using classes), dynamic and strongly typed programming language that is used for a wide range of applications. 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: Jun 16, 2012 · There's the != (not equal) operator that returns True when two values differ, though be careful with the types because "1" != 1. Mar 21, 2023 · In Python this is simply =. source Otherwise, any special meaning of _ is purely by Mar 16, 2017 · Why is it 'better' to use my_dict. source Otherwise, any special meaning of _ is purely by Aug 5, 2010 · What does the >> operator do? For example, what does the following operation 10 >> 1 = 5 do? Nov 29, 2011 · In Python, for integers, the bits of the twos-complement representation of the integer are reversed (as in b <- b XOR 1 for each individual bit), and the result interpreted again as a twos-complement integer. 96 What does the “at” (@) symbol do in Python? @ symbol is a syntactic sugar python provides to utilize decorator, to paraphrase the question, It's exactly about what does decorator do in Python? Put it simple decorator allow you to modify a given function's definition without touch its innermost (it's closure). keys() will still have the same problem with changing the dictionary size during iteration. keys() over iterating directly over the dictionary? Iteration over a dictionary is clearly documented as yielding keys. The reified form of the ~ operator is provided as operator. May 5, 2011 · As far as the Python languages is concerned, _ generally has no special meaning. It is a valid identifier just like _foo, foo_ or _f_o_o_. 10: In a case pattern within a match statement, _ is a soft keyword that denotes a wildcard. It appears you had Python 2 in mind when you answered this, because in Python 3 for key in my_dict. There's also the else clause: Mar 21, 2023 · In 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. Aug 5, 2010 · What does the >> operator do? For example, what does the following operation 10 >> 1 = 5 do? Nov 29, 2011 · In Python, for integers, the bits of the twos-complement representation of the integer are reversed (as in b <- b XOR 1 for each individual bit), and the result interpreted again as a twos-complement integer.
