I am trying to make a small flash card program for my kids. Here is what I have come up with so far, I was hoping if I reassigned the variables in the button function it would randomly pull a new list item. But that does not seem to be the case. I know my code is not he prettiest,

Python uniform random number generation to a triangle shape
I have three data points which I performed a linear fit and obtained the 1 sigma uncertainty lines. Now I would like to generate 100k data point uniformly distributed between the 1 sigma error bars (the big triangle on the left side) but I do not have any idea how am I able to do that. Here is my code
MySQL: Update multiple rows with random values
I have a table called rainfall. It has 2 columns (sensorID, area, time, rainfall, redalert) I want to fill the time column with random times in intervals of 5 minutes (e.g 12:55, 04:30, 07:45) . I managed to get the random times by using this Python code: The problem is that this code fill all rows in time with 1
How to lightly shuffle a list in python
I have this issue where I would like to shuffle a list, but only do so slightly. Say, I want only a small number of elements to be moved. Is there a simple way to get this done? Right now the best I can think of is building my own method be hand, but is there some way to use
Create a matrix with np.random.normal
I need to create an nxn matrix in which the numbers in the cells are distributed following a Gaussian distribution. This code may not go well because it fills a cell with a sequence. how can I do? Answer Edited for border of zeros np.random.normal takes a size keyword argument. You can use it like this:
Using random and shutil to move files in loop in python
I have a small problem. I am trying to move 20×500 images in 20 predefined folders. I can make this work with just 500 random images and I have identified the problem; I draw 500 random files, move them and then it tries doing it again but since it doesn’t update the random list, it fails when it reaches an
How to generate a random sample of points from a 3-D ellipsoid using Python?
I am trying to sample around 1000 points from a 3-D ellipsoid, uniformly. Is there some way to code it such that we can get points starting from the equation of the ellipsoid? I want points on the surface of the ellipsoid. Answer Here is a generic function to pick a random point on a surface of a sphere, spheroid
Python random.choice same output
I’m trying to random some strings in a variable, And when I’m running my script all of them are the same every time, I like to random my variable every time I’m calling it, like, Answer This is basically the same as A variables value only changes when you assign it: If you want a new random value, you need
Is numpy.random.choice with replacement equivalent to multinomial sampling for a single trial?
I understand that strictly on concept, they are different. But in a single trial (or experiment) for numpy.random.multinomial, is it sampling the same way as numpy.random.choice though giving a different view of the output? For example: Output gives the identity of what was picked in the array [0,1,2,3,4,5] and Output gives the number of times each choice was picked, but
How to generate a random UUID which is reproducible (with a seed) in Python
The uuid4() function of Python’s module uuid generates a random UUID, and seems to generate a different one every time: I would like to be able to generate the same random UUID every time I run a script – that is, I’d like to seed the random generator in uuid4(). Is there a way to do this? (Or achieve this
