Why 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. 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. Since is for comparing objects and since in python 3+ every variable such as string interpret as an object, let's see what happened in above paragraphs. In python there is id function that shows. 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.

Unary arithmetic and bitwise/binary operations and. 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. (a != b) is true. The simple answer is = is an assignment operator, == is a comparison operator. And you are wrong in saying that == can be used in any situation when = works. For example if i wanted to. 1 in python 2. 6 the '%' operator performed a modulus. I don't think they changed it in 3. 0. 1 the modulo operator tells you the remainder of a division of two numbers.
