From collections import counter c = counte. The first, [:], is creating a slice (normally often used for getting just part of a list), which happens to contain the entire list, and thus is effectively a copy of the list The second, list(), is using the actual list type constructor to create a new list which has contents equal to the first list. Is the a short syntax for joining a list of lists into a single list ( or iterator) in python For example i have a list as follows and i want to iterate over a,b and c. Let summarize the differences between list.of and arrays.aslist list.of can be best used when data set is less and unchanged, while arrays.aslist can be used best in case of large and dynamic data set.
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) Given a dataframe, i want to groupby the first column and get second column as lists in rows, so that a dataframe like A b a 1 a 2 b 5 b 5 b 4 c 6 becomes a [1,2] b [5,5,4] c [6] how do i do this? 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 just need to know if one e. If we need to find an element from the list, then we can use the find and findall extensions method, but there is a slight difference between them 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 List<string> optionlist = new list<string> { Since a list comprehension creates a list, it shouldn't be used if creating a list is not the goal
So refrain from writing [print(x) for x in range(5)] for example.
