There are two advantages of using this approach. You don’t have to create copy of list to iterate over elements You can combine other iterables such as set and tuple as well Using Additional Unpacking Generalizations There is another way to combine two lists in python>=3.5 version.Additional...

The script lists all files in the input directory and begins processing each one that matches the expected file extension (defined in step 1 as .raw). For each valid input file, the code: Extracts the base name of the file (name without extension). Prints an ongoing status message indica...
to_datasetwill fail for unnamed DataArrays, but_to_temp_dataset()will succeed. It seems to me like we want lists of unnamed DataArrays to work (like in the first example), so call_to_temp_datasetwhen needed. Maybe@shoyerhas an idea on how to implement that cleanly. ...
numbers) that are unique in that set. For example, if you were to do a set operation on the array[1,1,2,3]Ruby will filter out that second 1, even though 1 may be in the resulting set. So be aware that these set operations are different than list operations. Sets and lists are...
Consider these two alternatives from R and Python. Either way, reading and manipulating Excel files is a daily task of any R data analyst. The readxl package comes with everything you need to make communication as easy as possible. If you’re an Excel expert and just starting with R, ...
