## Generate random binary matrix constrained to no null row

I want to generate a random binary matrix, so I’m using W=np.random.binomial(1, p, (n,n)). It works fine, but I want a constraint that no row is just of 0s. I create the following function: It also works fine, but it seems to me too inefficient. Is there a faster way to create this constraint? Answer When the matrix is large,

## Tkinter Window: TypeError: can only concatenate str (not “int”) to str

I’m having trouble solving the Concatenate Error when it’s present in a Tkinter Window. I tried using multiple methods but, they didn’t work to well with what I’m trying to do. I’m trying to make it so where, at the click of a Tkinter button, it would randomly choose a value between 0 and 100. If the random value is

## randomizing list and exporting the results as unique set of 4 strings

I have wanted to randomize list of strings, 9 different strings and then printing out the strings into unique set of four then exporting it into txt file. Here is what I have tried so far, but I am not sure how to set them into groups of four. I want the print outcome to come out in an example

## Return random numbers from lists of varying size with weights

I would like to split existing data for a train-test-split in python. Functions like sklearn.train_test_split() typically choose evenly distributed values as testdata. But since I want to check, whether my model can deal with skewed data (more training data on “the left side of the function”) I need to weigh the split more towards the left side of my data.

## Problem: In dataset i have data of country,state and city. Where some state and city name is 0.so,I want to replace “0” value of state with city name

## How to sample data points for two variables that has highest (close to +1) or lowest (close to zero) correlation coefficient?

Let’s assume that we have N (N=212 in this case) number of datapoints for both variables A and B. I have to sample n (n=50 in this case) number of data points for A and B such that A and B should have the highest possible positive correlation coefficient or lowest correlation coefficient (close to zero) for that sample set.

## Is there a way of selecting all records of a certain ID after randomly selecting the IDs?

I have a number of values per ID in this format: I want to randomly select IDs but keep all values per ID, so for example, if I wanted to get 2 random IDs; the outcome would look like this: Giving me, ID 2 & 5. Answer Use numpy.random.choice to select random values then select them. Edit: please read the

## Coin flip based on randint returns false mostly?

I am writing a game in python using Pygame. In the game, I am setting a variable to a random value of either True or False using this statement: After running this 2 to 3 times, it kept returning False. At first, I thought that this was probably a coincidence, but after running this like 10 times, it returned True

## random number generating function as argument in python

I want to pass a function which generates random normal numbers to another function, do some calculations and pass again the random function x times. At the end there should be a Dataframe with x colums with diffrent randomly generated outcomes. My code looks like this: But this gives me always identical columns. Answer I don’t think you can pass
