Using a for loop index in .loc to access a rolling slice of a dataframe?
I want to create rolling slices of a master dataframe. I’m trying to measure the difference in outcomes over rolling periods. The master dataframe has 120 years of data and I want to create rolling slices of 10 years of a column(s), i.e slice one goes from year 1 to 10, slice 2 goes from year 2 to 11, etc…
How to create and update the same list from another list
i have two lists: Now i need another list that updates value like: How do i update list as mentioned above? Answer Your question is not extremely clear but it seems you’re looking for something like this: You can keep an offset of the index to add elements to new lists based on the indices provided.
Replacing list comprehensions with pandas and numpy Python
The function below uses slices to get the maximum value between 2 indexes at once. So it gets the maximum value between 0 and 10 and then 10 and 12 and such. The function is derived from the answer to this post post. Is there a way I could could replace the list comprehensions in the form of a pandas
How can I print a statement in Python to show the results of a mathematical operation on a Pandas Dataframe?
So I’ve got a simple summary dataframe of sales by gender that goes: All I want to do now is to return a line in Python that reads: The mean gap in the amount sold is 16.67% This is simply 30 – 25 divided by 30, and multiplied by 100; and I want a % sign at the end. I
Why don’t Multi-dimensional (non-numpy) list slices work (anymore?)
Didn’t we used to… I remember being able to type in something like and getting back something like If I type the code above, I will get the following error (in Python 3.7): But if I call just one dimension, it works fine: What’s the Direct, Easy Slice Syntax? While I’m mildly interested if things changed or if I am
DICOM slicing orders in python

Is it possible to unpack values from list to slice?
I’m trying to use values in list to select part of word. Here is working solution: but I wonder if is it possible to shorten it? Something like this comes to my mind: It produces: Answer You can use the built-in slice (and need to name your list differently to be able to access the built-in):
Skip every nth index of numpy array
In order to do K-fold validation I would like to use slice a numpy array such that a view of the original array is made but with every nth element removed. For example: If n = 4 then the result would be Note: the numpy requirement is due to this being used for a machine learning assignment where the dependencies
Pandas Dataframe datetime slicing with Index vs MultiIndex
With single indexed dataframe I can do the following: Date time slicing works when you give it a complete day (i.e. 2016-01-01), and it also works when you give it a partial date, like just the year and month (2016-01). All this works great, but when you introduce a multiindex, it only works for complete dates. The partial date slicing
