## Is it possible to create a random shape on an image in python?

I need to create some spots on an image. The spots are of irregular shape (mainly I was trying to add a big circle then trying to add smaller circles on the edges of the big circle so it gets an “irregular” circular shape). Here I just showed one circle in the example. As I have a directory full of

## Random list item, but unable to choose the same item twice

Is it possible to run a loop, that chooses a random list item, but is unable to choose the same one twice in a row. I’ve tried running it in a thread and with Clock.schedule_interval Im not sure how to keep the loop and GUI running simultaneously. When the interval goes off, it “resets” the loop. therefore being able to

## Connecting to random points in a 2d numpy array based on distance

I have a 2d numpy array and select a random coordinate position (say 10×10 array and start at position 2,3). I want to randomly connect to 40% of the other points in the 2d array effectively generating a list of tuples [(x1, y1), (x2, y2) …] where the list is 40% of the other coordinates. An additional constraint, however, is

## Python: Generate random letter then Keystroke said letter

(I am using Python under Mac OS) Hey Guys, i am looking for a way to random generate a letter (a-z) and then keystroke it. The way I usually do keystrokes is: cmd = “”” osascript -e ‘tell application ‘System Events’ to keystroke “insert_letter_here”‘ “”” os.system(cmd) This won’t accept random.letter since it would keystroke the exact spelling of random.letter. Does

## I’ve declared variable “x” but i did not call it, is it ok to not call variables that have values assigned?

In this program, the user will enter the total amount of numbers in a list. the random module will generate random numbers between 1 to 30. Then all the numbers from the list will be added together. I’ve tried to use the variable x but it doesn’t give the results I want, does anyone know a better/simpler way of creating

## Seedable CSPRNG for python?

With the random module, you are able to seed it to get the same values every time. import random random.seed(1) print(random.randint(1,100)) # outputs 18 every time lst = [1,2,3] random.shuffle(lst) …

## Python: generate 5 random int (every has own range) with fixed sum

import random #lets take kg(for Total) for better understanding Total = random.randint(40, 110) #For example Total=100 kg and this is 100% Total = (a+b+c+d+e) Each value in Total has own range …

## Sample points from a hyperboloid

A hyperboloid has the formula -x^2/a^2 – y^2/b^2 + z^2/c^2 = 1. How can I generate samples from this hyperboloid in Python? (Say, with a=b=c=1.) I was thinking to pick random x and y in [0,1] and then …

## Fill Excel cells with random numbers

I have a question about how to fill some cells in Excels with random values? For example, I have a part of the code with: numbers_random = (random.random() for _ in range(10)) worksheet.write(‘A1:J1’, …
