You must be able to see your current working directory. How do we know the true value of a parameter, in order to check estimator properties? Again, it doesn"t work for 3 when keys are not strings. Don"t use what you see in the formerly accepted answer: In Python 2, you create two lists in memory for each dict, create a third list in memory with length equal to the length of the first two put together, and then discard all three lists to create the dict. If the name is resolved successfully (which means that another module has already loaded it) will be then be made available to the local namespace otherwise, jump into step 2. Connect and share knowledge within a single location that is structured and easy to search. z = dict(list(x.items()) + list(y.items())). This means you can put a function inside a class but you can"t access the instance of that class (this is useful when your method does not use the instance). Exchange operator with position and momentum.

See that in the example below: datetime2 is not an instance of DateTime? Let"s assume that we want to create a lot of Date class instances having date information coming from an outer source encoded as a string with format "dd-mm-yyyy". The fact that this only works for string keys is a direct consequence of how keyword parameters work and not a short-coming of dict. When you are using an IDE that has autofill, Pycharm for example. Does balls to the wall mean full speed ahead or full speed ahead and nosedive? Does aliquot matter for final concentration?

As keys must be hashable and are usually therefore immutable, it is pointless to copy them: Coming up with contingencies for other value types is far beyond the scope of this question, so I will point you at my answer to the canonical question on a "Dictionaries of dictionaries merge". @staticmethod means: when this method is called, we don"t pass an instance of the class to it (as we normally do with methods).
