I’m currently trying to create a conical gradient, and it kind of works. However, it doesn’t look quite right and I can’t wrap my hand around to why: The line that goes up from the center is slightly …
I have a huge data-frame (>20m rows) with each row containing a timestamp and a numeric variable X. I want to assign a new column where for each row the value in this new column is the average of X …
How do I append values in an empty numpy array? I have an array of values that I want to perform a mathematical equation on and from those values I want to append it to a new empty array. What I have …
I’m trying to replace equal consecutive numbers in a list to nan. I having problems to replace all values when there is a odd number of equal consecutive numbers. This is my code, very simple: list= […
The std pandas function below calculates the standard deviation of every nth value defined by number. So it would take the the values of PC_list with indexes [0,1,2,3,4,5] and calculate the standard …
Is there any way I can fit two independent variables and one dependent variable in numpy.polyfit()? I have a panda data frame that I loaded from a csv file. I wish to include two columns as …
