I’m trying to randomize all the rows of my DataFrame but with no success. What I want to do is from this matrix to this I’ve tried with np. random.shuffle but it doesn’t work. I’m working in Google Colaboratory environment. Answer If you want to make this work with np.random.shuffle, then one way would be to extract the rows into

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’, …
