Can we creat a 3x3 matrix using a while loop in python-CodePudding

As we creat a matrix using for loops in python, I would like to know that can we creat it using while loops.

CodePudding user response：

In this link there is the possible solution Python matrix

In reality, the while loop is used to satisfy a condition, instead the for loop is used when we know exactly how many times to execute it. Numpy is also used to create a matrix in Python.

Here is a possible solution, but that’s not the optimal solution:

from random import randint
matrix = []
i=0
while i < 3:
    j = 0
    n = []
    while j < 3:
        number = randint(1,100)
        n.insert(i,number)
        j = j 1
    matrix.append(n)
    i = i 1
print(matrix)

In this link you can find your answer https://www.geeksforgeeks.org/take-matrix-input-from-user-in-python/

you can also use numpy

import numpy as np
matrix = np.zeros((dim1,dim2))
# this will generate matrix of dim1 x dim2.

you can also refer to numpy documentation.
