But in terms of creating an empty list or dict, are there any differences? I have a piece of code here that is supposed to return the least common element in a list of elements, ordered by commonality From collections import counter c = counte. Don't use quotes on the command line 1 don't use type=list, as it will return a list of lists this happens because under the hood argparse uses the value of type to coerce each individual given argument you your chosen type, not the aggregate of all arguments You can use type=int (or whatever) to get a list of ints (or whatever) You must be sure that at runtime the list contains nothing but customer objects
Critics say that such casting indicates something wrong with your code You should be able to tweak your type declarations to avoid it But java generics is too complicated, and it is not perfect Sometimes you just don't know if there is a pretty solution to satisfy the compiler. How is it possible to initialize (with a c# initializer) a list of strings I have tried with the example below but it's not working
For example, 17 is element 2 in list 0, which is list1[0][2]: In c# if i have a list of type bool What is the fastest way to determine if the list contains a true value I don’t need to know how many or where the true value is I just need to know if one e. The list is the part of python's syntax so it doesn't need to be declared whereas you have to declare the array before using it
List is an interface, you cannot instantiate an interface, because interface is a convention, what methods should have your classes In order to instantiate, you need some realizations (implementations) of that interface. How can i list all files of a directory in python and add them to a list?
